Simple permanent tissues are Parenchyma, Chlorenchyma, Aerenchyma, Collenchyma and Sclerenchyma, on the other hand, main complex tissues are Phloem and Xylem. Plant Tissues: Plant tissues are of two main types, viz. Special proteins, known as contractile proteins help the muscle to contract and relax, thereby causing movement. The different types of plant tissues are: 1. The evaporation of excess water from the plant through the stomata is known as transpiration. Also Read: Class 9 Science: Sound. Muscle cells are elongated and large sized, so they are called muscle fibres. Animal tissues are hence also specialized in their structure. This is a soft tissue that is very sensitive. Nervous Tissue : The nervous tissue, which contains densely packed nerve cells, […] Answer: There are four main types of tissues present in animal. List any four salient features of meristematic tissue. Neurons are the primary connectors that help the animal react to stimuli. Epithelial cells protect the underlying cells from mechanical and chemical injuries and bacterial or viral infection. These different types of cells coordinate to perform a function. The cells of this tissue are living, elongated and irregularly thickened at the corner. Chlorenchyma is a … They are long and narrow as the walls are thickened due to lignin, such cell walls are called lignified. Leverage Edu Tower, Xylem and phloem together constitute the conducting tissues in plants. Question 5. Tissues are responsible for all the major functions like respiration, digestion etc of the body. Right from the time we are made familiar with the functioning of the human body, we have always been taught the importance and uniqueness of every organ that the human body has. Tissues Class 9 Notes – Here We have provided summary and revision notes for Class 9 Science Chapter 6. Dendrons further branched out to form dendrites. All types of questions are solved for all topics. The nervous tissue is responsible for the reception and transmission of information between different parts of the body. Complex tissues are of two types: Xylem or wood and phloem or bast. Their main function is to help in the transportation of food and water vertically in the plants. Connective tissue. Hence, they are together known as vascular tissues. It consists of thin walled living cells. What are the types of plant tissues and their functions “A tissues may be defined as a group or collection of similar or dissimilar cells that perform a common function & have a common origin.” Classification of Plant Tissues : A plant body is made up of different kinds of tissue. The tissues present in the growing parts of the plant are not made up of dead cells. They are of two types: Epidermis and Cork. 2. A number of body parts are provided support by the cartilages. These are dead and thick walled cells. The sclerenchyma is mainly mechanical and protective in function. Tissues become organized to form organs and organs into organ systems. Vacuoles in these cells are either small or absent. Complex tissue is composed of more than one kind of cells. A neuron consists of a cell body (cyton or soma) with a nucleus and cytoplasm, from which long thin hair- like parts arise called dendrons. Nerve supply from autonomous nervous system. It acts as an insulator and regulates body temperature. ADVERTISEMENTS: Meristematic cells gradually divide and get differentiated to form permanent tissues. Answer: The simple tissues are made of one type of cells and complex tissues are made of one or more types of cells. It protects and supports the body. Neurons help the body respond to external stimuli through electrical signals. It results in increase in the hight of the plant, which is called primary growth. All these cells coordinate to perform a common function. These help repair organ tissues. These tissues are responsible for increasing the length and girth of the plant. ‘something’ and helping you leverage it! Animal tissues can be grouped into four basic types: epithelial, muscular, connective and nervous tissues. Plants, too, are built of tissues, but not surprisingly, their very different lifestyles derive from different kinds of tissues. Muscle cells are typically arranged in parallel arrangement allowing them to work together effectively. ‘ (a) Epithelial tissue present on the outer and inner lining of the body. The revision notes covers all important formulas and concepts given in … Permanent Tissue - It of two types: Simple and Complex tissues. There are four types of animal tissues in an animal body. Types of Complex Machines. Write differences between blood and lymph. Complex Tissues Tissues composed of more than one cell type are generically referred to as complex tissues. (ii) Complex permanent tissues: The complex tissues consist of more than one type of cells having a common origin. The tissues located in the growing parts of plants are known as Meristematic Tissues. Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. Cells individually cannot perform all the tasks of an organism. All these cells co-ordinate to perform common function. Ligaments: Bones are connected together through ligaments. Epithelial tissues are of following types— (1) Simple squamous epithelium (2) Stratified squamous epithelium (3) Columnar epithelium, and (4) Cubodial epithelium. In the chapter tissues class 9 notes, majorly, we will discuss two types of permanent tissues, i.e, Simple and Complex. The function of epidermis is the protection of plant from injury and infection. These are intercellular medium, connective tissue cells and fibers. They are two types, namely Xylem tissue and Phloem tissue. Simple 2. Bones: The bones are the basic structure of the body, over which various tissues and organs are wrapped and supported. Question 16. It transports gases, waste, hormones, and nutrients throughout the body. Let us also discuss the different types of connective tissue in our tissues class 9 notes. Nervous tissue contains highly specialized unit cells called nerve cells or neurons. The axon connects the body to the end of the neuron and helps in signal transmission. These blood corpuscles and cells are: Red blood corpuscles (RBC) or erythrocytes, White blood corpuscles (WBC) or leucocytes. Function: They form primary structure of the plant. Skeletal connective tissue forms the endoskeleton of the body of vertebrates. Through NCERT solutions for class 9 science chapter 6 tissues, you will get to know the approach of solving a question. IF the tissues are composed of more than one type of cell, and they work together as a unit, performing many functions, then they are called COMPLEX TISSUES. Transpiration as well as exchange of gases through the stomata happens through the guard cells. Basal part of cell bears oval nucleus. All three types of plant cells are found in most plant tissues. Complex 3. All right reserved. A-258, Bhishma Pitamah Marg, Mention the two types of complex tissues and write their functions. Cells of this tissue are elongated and flattened. Your email address will not be published. The cells of the epithelial tissue are generally permeable, and there is no space between them. Tracheids 2.

The cells of connective tissue are loosely spaced and embedded in an intercellular matrix. Cuboidal: Salivary ducts and kidney tubules are generally cuboidal in shape. Cartilage provides support and flexibility to the body parts. As for all animals, your body is made of four types of tissue: epidermal, muscle, nerve, and connective tissues. It produces an increase of length of organ such as leaves and internodes. Answer: Permanent tissues are made of meristematic cells, that has definite form and shape and have lost the power to divide and differentiate and are of three types- simple, complex and special. The complex tissues in a plant deal with moving nutrients and water to the leaves, while removing the products of photosynthesis from the leaves. The place of injury in plants is healed up by the formation of new cells by meristems. The adipose tissue is abundant below the skin, between the internal organs (e.g., around the kidney) in yellow bone marrow. Complex permanent tissue contains different types of cells. Get chapter notes for CBSE Class 9 Science, chapter 6: Tissues (Part-I). Dark and light bands (cross striations) present.
