how many types of simple tissue

parenchyma. Often the secondary wall is so much thickened that the central lumen is almost obliterated (Fig. Name the types of nitrogenous bases present in the RNA. Paren­chyma with thin cellulose wall can also serve as a supporting tissue due to turgid condition of the cells, what is particularly evident in herbaceous plants. (5) The intercellular spaces may or may not be present. Find an answer to your question how many types of simple tissue 1. The cells are arranged like tiles on a floor, so, it is also known as pavement epithelium. 3. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? Like parenchyma it can undergo reversible changes and retain the capacity of cell division. They are usually poly­gonal in cross-section. Three main different types of tissue are follows-Epidermal tissue - It is composed of closely packed cells which have thick walls. Xylem and Phloem are complex permanent tissues and are found in the vascular bundles in the plants. Of course some fibres may retain protoplast even up to the permanent stage. In biology, tissue is a cellular organizational level between cells and a complete organ.A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. 535) is also a simple tissue consisting of one type of elements. Epithelium (/ ˌ ɛ p ɪ ˈ θ iː l i ə m /) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.It is a thin, continuous, protective layer of cells.Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. Types of Epithelial Tissue. In herbaceous stems collenchyma usually continues to function permanently, because secondary increase in thickness is poor in these organs. The fibres have great commercial value. Sclerenchyma is another simple tissue nicely adapted for mechanical function. Dense regular tissue is made out of tightly packed clumps of collagen fibers, running in parallel directions. Understanding how tissues work is fundamental to understanding how organs work. In this lesson, learn more about the types of tissue and how each functions for a different purpose. Let us learn a little bit about each type. Fibres usually occur as groups or sheets along the longer axis of the body in different parts of the plants. This tissue is normally absent in underground organs, though it may rarely occur in roots, particularly when they are exposed to light. The air spaces give buoyancy to the plants in addition to normal aeration. Three different types of tissues- epidermal tissues, ground tissue and vascular tissues. (2) Aerenchymaparenchyma contai air cavities. (2) They are with equal diameter, more or less spherical or star shaped in Scirpus, and usually with intercellular spaces. There are eight basic types of epithelium: six of them are identified based on both the number of cells and their shape; two of them are named by … They are of three types as. Epidermal cells with cutinized outer walls have protective function. Content Guidelines 2. They may also occur singly as idioblasts as in the leaflets of Cycas. Dense connective tissue is composed of large amounts of closely packed collagenous fibers. Parenchyma cells. 3- Simple columnar epithelium is made up of a single layer of tall columnar cells, The nuclei are ovoid and close to the base of the cell, It has 2 types: Non-ciliated simple columnar epithelium: their free surface is smooth and may have microvilli. Parenchyma cells. A term annular collenchyma has been used by some Workers for this type which has lost the angular appearance. Ask your question. Meristematic plant tissue, at the central point, is undifferentiated and ready to divide into any other type of plant cell.Meristematic cells divide asymmetrically.This means that one plant remains undifferentiated, while the other cell takes on a more specialized form. The cells usually divide in a particular plane. The plastids are present in the form of; The crystals are absent and the endoplasmic reticulum is poorly developed. Differentiate between parenchyma, collenchyma and sclerenchyma on the basis of their cell wall. Pseudo-stratified epithelium (1). The collenchymas usually remain in the hypodermis of stem and also in the base petiole and pedicel. This type of simple tissue shows the following characteristics: In some plants cellulose-rich and pectin-rich layers alternate on the wall. These cells with that all-important function photosynthesis are also called chlorenchyma. These different types of cells coordinate to perform a function. All these fibres are typically elongate bodies with simple pits. Though typical fibres have acute ends, blunt and even branched ends may also be noticed. Type # 1. 534 E, F & G). The plant tissue in which the process of growth has stopped are called the permanent tissue and it originates from both primary and secondary meristematic tissue. They are noticed most commonly as homogeneous bands beneath the epidermis, or they may occur as disconti­nuous patches. leaf of banyan. in length. Tissues are groups of cells that work together to do a job in the body. The different types of epithelial tissues are given below. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body. In the mesophyll of the leaves they are slightly elongated. Such changes can be detected through The walls are considerably thickened, often heavily lignified with simple pits. The parenchymatous cells of leaves and sometimes other organs like stem contain enough chlorophyll. As regards classification of fibres a number of systems have been in use. (a) Simple tissue including parenchyma, collenchyma and sclerenchyma. You will see how their shape adapts according to the functions that they perform. Medically, the simple epithelium is further divided into 2 types: simple cuboidal epithelium and simple … Join now. Click here►► Next Often fibres are put in two groups, viz., intraxyllary fibres or wood fibres, and extraxyllary fibres, also called bast fibres. Connective tissue integrates the various parts of the body and provides support and protection to organs. One particular type is called pseudostratified because a single layer of cells having varying heights gives the appearance of being stratified. Thus parenchyma is the precursor of all other tissues. All … Simple pits may be present both on the thin and thick portions of the wall. Two other types of connective tissue are dense regular tissue and dense irregular tissue. Parenchyma is simple and consists of thin-walled cells which are non-specialized in structure. The simple tissue, parenchyma shows the following characteristics: - Cardiac muscle contracts the heart to pump blood. Though these are the two forms, intermediate types are not uncommon. Skeletal muscle moves bones and other structures. The types are: 1. Bodies of lower plants are made of parenchyma cells. Muscle tissue allows the body to move. Due to presence of active protoplast this tissue is the seat of all essential vegetative functions like photosyn­thesis, storage of food matters, secretion and excretion. Tissues are groups of cells that work together to do a job in the body. Tissues of same kinds compose simple tissue. Cross-section of a flax plant stem with several layers of different tissue types: 1. pith 2. protoxylem 3. xylem 4. phloem 5. sclerenchyma 6. cortex 7. epidermis. Simple cuboidal epithelium-consists of a single layer of cells that are roughly square in shape when cut in cross-section. Columnar epithelium (4). In growing organs it provides sufficient tensile strength till more effective mechanical tissues like sclerenchyma are differentiated. Simple Epithelium (II). Parenchyma cells retain the potentialities of cell division. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Last name of tissue describes shape of cells. Squamous—cells are wider than tall (plate-like) – “squashed” Cuboidal—cells are as wide as tall, like cubes; Columnar—cells are taller than they are wide, like columns; In this example we see air sacs of lungs We find these types of cells in kidney tubules. Parenchyma cells occurring in xylem and phloem help in the conduction of water and food matters in solution. The term tissue engineering was introduced in the late 1980s. They are living and have been found to contain starch, oils, resin and crystals and are thus thought to have storage function. Xylem and phloem are examples of complex tissues. Simple tissues are made up of one type of cells which coordinate to perform a common function. Simple—one layer of cells; Stratified—more than one layer of cells; Last name of tissue describes shape of cells . Ø Five types of simple epithelial tissue occurs in animals: (1). Parenchyma cells have usually thin cell wall made of cellulose. They are abundantly present in cortex, pericycle, xylem and phloem. Answered How many types of simple tissue 2 It is composed of cellulose and pectic materials with high percentage of water. Learn types of tissue with free interactive flashcards. Ø Simple type and composed of single layer of cells. Ground Tissue System: The system is formed from ground meristem or partly plerome and partly periblem that forms the interior of plant organs with the exclusion of epidermal and vascular systems. They are: (i) Angular collenchyma (Fig. (Fig. The permanent tissues can be classified into three major types on the basis of its constituent cells. The meristematic cells are also parenchymatous in nature. There are three major types of simple tissues viz., parenchyma, collenchyma and sclerenchyma. They are parenchyma, collenchyma, and sclerenchyma. Water-storing parenchyma cells are large with prominent vacuoles, scanty chloroplasts and thin cell wall. Irregular shapes as a result of folding (Fig. The cells have active protoplast. (b)Complex tissue including the xylem and phloem. Simple epithelium as one of the types of Epithelial Tissue Simple Epithelial. (adsbygoogle = window.adsbygoogle || []).push({}); For example, nerve cells and circulating blood cells are present in virtually all organs. Functions of secretion and absorption e.g. In some xerophytic plants they are specially adapted for storage of water. Tissues in organs are precisely arranged so that they can work in harmony in performing organ functions. It can very successfully withstand strains and stresses like flexion, compression and longi­tudinal pull in cylindrical bodies and shearing stresses in leaves. Simple epithelium tissue. Simple Plant Tissue. The following points highlight the three types of simple permanent tissue. Types … The four types of fabrics Epithelial tissue. Though these are the three types of collenchyma recognised, it should be noted that sharp distinction between them hardly exists. Compound Epithelium (III). Share Your Word File An "Orchestra" of Tissues. The uneven thickening of these cell walls makes it partially hard giving mechanical support. Ø Every cell in the epithelial layer connects to the basement membrane. Share Your PPT File. A single organ can have different types of epithelial tissue based on the substances to which different surfaces are exposed. They occur singly or in groups in the soft tissues like pith, phloem flesh of fruit and also in seed coat and fruit walls.They provide mechanical support to the plant body. The fibers are flexible and capable of adapting to pressure. Which organelle is known as “power house” of the cell? They are parenchyma, collenchyma, and sclerenchyma. How many primary tissue types are found in the human body? Muscle tissue 3. Type # 1. Unlike simple permanent cells which look the same and are made up of one type of cells, complex permanent tissues are made up of more than one type of cells. (1) The parenchyma of the epidermis protects the plant organs. Primary pit fields may be present. Explain its significance. It is a plant tissue formed of thin and densely packed cells, meant to separate the inside of the organisms from the outside. When the epithelium is composed of a single layer of cells, it is called simple epithelial tissue and those containing two or more layers of cells are called stratified epithelial tissues. 2. TOS4. Connective tissue connects, supports, binds, and separates organs and tissues, forming a framework to support body tissues and organs, for structural and metabolic purposes. On the base of the cell layer, the simple types of epithelial tissue are: Simple Epithelial; Stratified Epithelial; The epithelium which is made up of a single layer of cell is known as simple epithelial tissue. The different types of epithelial tissues are given below. The term prosenchyma for the cells much longer than breadth had been used by early authors. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Cytoplasm is dense with many small vacuoles and large nuclei. Another type of connective tissue is dense or fibrous connective tissue, which can be found in tendons and ligaments. These fibres are put into two groups; libiriform fibres and fibre-tracheids (Fig. Browse more Topics under Human Body . e.g. Name them.3. 536B). The fibres of ramie, Boehmeria nivea of family Urticaceae may measure as much as 55 cm. The simple tissue Collenchymas can be classified into three major types on the basis of the ***thickening. Their walls exhibit lamellations. In leaves they may be present on both sides of the veins or along the margin. (v) The walls contain simple pits. Share Your PDF File Types of epithelial tissue. In view of the fact that diverse types of cells may be elongated, the term prosenchyma has gone out of use. Ciliated epithelium (5). Chloroplasts may also be present. ADVERTISEMENTS: The following points highlight the four main types of tissues seen in animals. Types of Simple Epithelium Simple Squamous Epithilium This tissue consists of thin flat, tile like polygonal or hexagonal cells with a centrally located oval or spherical nucleus. (1) It gives rigidity to plant body. The number of cell layers each epithelial tissue has falls into one of two categories: simple, which means 1-cell layer thick, or stratified, which means more than 1-cell layer thick. parenchyma; collenchyma; sclerenchyma. the stomach, or blood lines, vessels and the lung. They have been called gelatinous or mucilagi­nous fibres. In simple words, the connective tissue is a group of various cell that interlaced together and connect the various cell and structure of the body. Epithelial 2. Connective 3. A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.. Nervous tissues propagate information. image source: cnx.org/resources/837827bcce3b61b28ce6dbf6b8f8877b9025686d/403_Epithelial_Tissue.jpg (a) Parenchyma (b) Collenchyma (c) Sclerenchyma. Small pits, round or slit-like in appearance, are frequently pre­sent. Fibres (Fig. 1)Simple Squamous Epithelium 2)Simple Cuboidal Epithelium 3)Simple Columnar Epithelium 4)Simple Ciliated Columnal Epithelium Epithelial tissue, or epithelium, can be described as leaves or layers of tissue lining surfaces in the human body . The value of sclerenchyma as the most effective mechanical tissue is due to the interlocking of the ends and considerably thickened walls. These cells have a definite shape and configuration but they do not have the power of division. You will see how their shape adapts according to the functions that they perform. Tissue engineering, scientific field concerned with the development of biological substitutes capable of replacing diseased or damaged tissue in humans. Sites: lining most of … Ans. The homogeneous group of non-meristematic or permanent cells having similar structure, function and origin is collectively known as simple tissue. The parenchyma of vascular bundle develops from procambium ; but that of secondary vascular tissues develop from inter-fascicular cambium. How many type of simple tissue ? Parenchyma – The cells of this tissue are living, with thin cell walls. The Types of Tissue We have determined that we are made up of four different types of tissue. Our mission is to provide an online platform to help students to share notes in Biology. Thus they are concerned in increase in thickness and also in healing of wounds and formation of adven­titious roots and buds. How the vascular cambium is responsible for secondary growth? Often thick and lignified walls are present in the parenchyma cells of xylem, particularly secondary xylem. Monohybrid Cross; Bones in Human Body; pH of Blood; Human Body System; List of Body Systems; Urea; Hinge Joints; Parts of Human Leg; Skull; Peyer’s Patches; Connective Tissue Definition. How are simple tissues different from com… Harmangill0013 Harmangill0013 28.05.2020 Science Secondary School AZE Exercises Define the term "tissue". How is the air cleaned before it enters the alveoli? Learn more about tissues in this article. (adsbygoogle = window.adsbygoogle || []).push({}); They commonly occur as continuous bands or isolated strands in the cortex, in the pericycle, as caps or sheaths on and around the vascular bundles and as patches in the leaves of monocotyledons in particular. Squamous Epithelium: Ø They are flattened one layer thick epithelium. The shape and size of the cells constituting this tissue are variable. A Tissue forms part of an organ in plants or animals. The functions are as follows: Figure 13.10. Learn about Connective Tissue here. These are really something intermediate between the tracheids and fibres. The cells usually divide in a particular plane. Connective Tissue 3. 536) are very much elongate sclerenchyma cells usually with pointed needle-like ends. It (Fig. 535D). (4) The primary pit fields are present. Join now. The presence of hard elastic secondary wall with low water-content distinguishes sclerenchyma from collenchyma possessing plastic primary walls with high percentage of water. Parenchyma tissue are lignified as observed in the endosperm of date-palm. (2) The cells are elongated containing scanty vacuolated rotoplasm, appear polygonal in cross section. The combination of one or more types of tissue forms the organs, the body work unit. In storage region the walls of the cells may be considerably thick due to deposition of hemicellulose, as formed in the endosperm of Phoenix (date- palm). The term aerenchyma is usually attributed to this type of parenchyma. Answer: Permanent tissues are a group of living or dead cells which are formed by meristematic tissues that have lost their ability to divide. (1) The living cells with unevenly thickened walls composed of hemicellulose and pectin. Jute, hemp, flax, ramie, etc., are common sclerenchyma fibres. In angiosperm: Vegetative structures …performing only one function are simple tissues, while those composed of more than one cell type and performing more than one function, such as support and conduction, are complex tissues. Roots of Monostera; stems of Ma Salvia, Calotropis. Fibres occurring outside xylem—the so-called extraxyllary fibres-are often called bast fibres. It is usually absent in the monocotyledons, both stems and leaves. Some xylem and phloem fibres develop partition walls later, e.g., Vitis, which are called septate fibres (Fig. Parenchyma – The parenchyma tissue is located in the soft parts of the plant such as cortex and pith. The shape of the cells is variable, the short ones being more or less like parenchyma and the longer ones re­sembling the fibrs, which may have, tapering ends often overlapped and inter­locked like fibres. Name them. Fibres associated with xylem differ from other fibres particularly in the occurrence of bordered pits. (3) The cells contain large nucleus and large vacuoles. Cells can be oval or round in shape. As a result the cells appear like plates or bands. Describe the different types of simple permanent tissue. Specialised parenchy­matous cells which produce and store tannins, oil and crystals of calcium oxalate are referred to as idioblasts. The Simple Columnar Epithelium is tissues composed of a single layer of long epithelial cells which are usually seen in an area where absorption and secretion are important facts. Types of Epithelial Tissue. Though normally collenchyma cells are narrower and longer than parenchyma, the two types of tissues very often intergrade; even transitional forms may occur. While superior tissue embrace xylem and phloem. At maturity these cells lose protoplast and become dead. So, it is considered to be the most primitive tissue, both phylogenetically and ontogenetically. Simple tissue occur in all parts of plant and superior tissue solely occur in vascular space. Mesophyll is made up of two types of … name them. These structures help attach muscles to bones and link bones together at joints. Here we shall discuss about the simple tissue of plants. There are several basic forms of plant tissue, formed from mostly identical types of cells. The component cells are usually ‘prosenchymatous’, a term once used to designate the cells much longer than breadth. Learn about Connective Tissue here. Parenchyma: The cells have thin cell walls made up of cellulose. (6) They may contain chloroplast, helping in photosynthesis. (4) It is the storage tissue for food and water. Those are : It generally develops from ground meristems. Types of Epithelial Tissue: By depending on functions is a specific location, there are different types of epithelial tissues. This tissue is called epithelium in animals and epidermis in plants. Epithelial tissues are identified by both the number of layers and the shape of the cells in the upper layers. Secondary meristems usually originate in this type of cells. (1) Angular : The thickening is localised to the corners of the cell making the cells Muscular 4. Four 1. Epithelial tissues can be classified according to cell shape. Permanent Simple Tissue. Ask for details ; Follow Report by Akashdeb984 29.05.2019 Log in to add a comment How many types of simple tissue?Explain. 534D), lobation, etc., are also not uncommon. Ground tissue system of leaves is called mesophyll. In ribbed organs like the stem and petiole of Cucurbita and square stems of members of family Labiatae, collenchyma occurs as patches in the ribs and at the corners of square stems. Type # 2. It occurs in the simple tissue of epidermis of root, stem and leaf, hypodermis, peric pith, medullary rays, mesophyll cells, mesocarp of fleshy fruits, embryo and endosp. Parenchyma (Fig. Choose from 500 different sets of types of tissue flashcards on Quizlet. The Parenchyma is walled living cells. *(3) Idioblast: specialized parenchyma with variable size storing oils, tannins and mineral crystals e.g. 534) is the most common simple tissue of the plants with relatively little specialisation. Let us learn a little bit about each type. Simple tissues are a collection of similar cells that perform a common function. harsh56772 harsh56772 1 hour ago Biology Secondary School +5 pts. The epidermis in plants serves the same function as it does in animals. 536G). Types of Simple Epithelium Simple Squamous Epithilium This tissue consists of thin flat, tile like polygonal or hexagonal cells with a centrally located oval or spherical nucleus. True/False. Each type of muscle tissue in the human body has a unique structure and a specific role. The wall is usually hard, uniformly thickened and lignified. (3) It is the major organ taking part in diffusion and osmosis. (2) It carries out functions like regeneration, repairing of tissues and reproduc In cross-section sclerenchyma cells look angular. Parenchyma tissue is of further two types: Aerenchyma and … Nervous tissue 4. A Tissue forms part of an organ in plants or animals. Answer Now and help others. Ø Five types of simple epithelial tissue … It mainly acts as a packing tissue, providing mechanical support. Those are : Squamous Epithelium – These are thin, flat cells that are closely packed. Disclaimer Copyright, Share Your Knowledge Log in. Unspecialised cells may approach 14-sided tetrakaidecahedron in shape. 1 ) Parenchyma A type of tissue is not unique for a particular organ and all types of tissue are present in most organs, just as certain types of cells are found in many organs. On the basis of thickening of the cell wall and arrangement of cells three forms of collen­chyma have been recognised. There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. In fact, highly thickened secondary walls of fibres of flax, Linum usitatissimum of family Linaceae are made of pure cellulose. Simple epithelium is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes similar to skins; the compound epithelium consists of two or more cell layers and has protective function. It is the outer most covering of the young plants, roots, stems and leaves. Muscular Tissue 4. Tissue In humans, there are four basic types of tissue: 1. Normally paren­chyma cells are polyhedral in shape with profuse intercellular spaces. Here is another anatomi­cal feature by which sclerenchyma fibres may be distinguished from parenchyma and collenchyma. Stems of Cucurbita, Beta and Datura. plz mark it as brainlist or follow me ; New questions in Biology. Ø Cells are very thin (thinner than the width of the nucleus). (I). Fairly large air cavities may be present in the parenchyma cells of aquatic plants in particular, where the volume of cavities is often greater than that of the cells. Ask your question. Epithelial Tissues: The cells taking part in this type of animal tissue have a regular, well-defined shape and scanty intercellular substance. Epithelial tissue Epithelial tissue & subtypes The epithelial tissue covers inner and outer layer/surface of the body, e.g. It is called the fundamental tissue of the plant, because it really constitutes the ground substance where other tissues remain em­bedded. That is, these tissues have undergone differentiation and are incapable of meristematic activities. Simple tissues making up the ground layers in plants. Human body is made of 4 types of tissues: Epithelium, Connective, Muscular, Nervous Tissue. 1. Due to continued thickening of the cell wall the lumen may look circular. The air that we breathe in is not sterile. By the early 1990s the concept of applying engineering to the repair of biological The Basic Types Of Tissue 1061 Words | 5 Pages. They may be broadly placed into two groups: very much elongate cells, called sclerenchyma fibres, and short cells, isodiametric or irregular in shape, known as sclereids or sclerotic cells. Simple Epithelium. Epithelial tissue is classified based on the cell shape and the number of cell layers. The following points highlight the three types of simple permanent tissue. It is possibly desirable to designate extraxyllary fibres on the basis of their topography as cortical fibres, pericyclic fibres and phloem fibres. Simple tissues are, well, simple. These are really the longest cells in the higher plants. How many types of elements tissue? There are different methods of deposition, but com­monly, the thickenings are confined to the corners of the cells. Collenchyma is an effective mechanical tissue of the growing organs, where it can give considerable strength and elasticity. These cells don’t store reserve food materials. 2 See answers shubhra28 shubhra28 Answer: there are three types of simple tissue in plants . Squamous Epithelium – These are thin, flat cells that are closely packed. Libiriform fibres actually resemble other fibres, whereas fibre-tracheids are regarded as reduced tracheids due to presence of bordered pits. This tissue is universally distributed in all the plants, the softer portions like epidermis, cortex, pith, pericycle whole or part, of stems and roots, mesophyll of leaves, pulp of the fleshy fruits, embryo and endosperm of the seeds being composed of parenchyma cells. Though chloroplasts may often be present, this tissue probably has no photo- synthetic function. Nervous Tissue. In Simple Epithelial Tissues, the cells of the tissue are arranged in a single layer. 535 A & B), the most common type, where deposition is-localised to the junctions between the cells. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions. ⚈ Simple permanent tissue is made up of structurally similar types of cells that perform a common function. 3.2 I-III) (i) Parenchyma: Parenchyma is the most common tissue which is morphologically and physiologically simple and unspecialized. The closely packed cells with thick walls have the capacity of increasing in surface and in thickness when the organ is still growing. What are antibiotics? Know more on different types of tissues and characteristics. As a result they often taken up star-like or stellate or armed appearance (Fig. Parenchyma; Collenchyma, and; Sclerenchyma. It occurs mainly on secretory and absorptive surfaces and seldom covers surfaces exposed to mechanical or chemical abrasions since it cannot effectively protect underlying tissues. On account of these similarities collenchyma is consider­ed a type of parenchyma specially adapted for supporting function. 535C). There are three types of ground tissue: parenchyma, collenchyma, and sclerenchyma. This typical collenchyma is a compact tissue consisting of irregularly arranged cells without intercellular spaces. The distribution of sclerenchyma in the plant members has direct relation to the strains and stresses to which they are subjected. Each cell has irregular boundaries. Welcome to BiologyDiscussion! Simple permanent tissues are again classified into three main types. Log in. The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. These tissues are of 3 types.
