NCERT Class 9 Science Chapter 6 Tissues Intext Questions (Solved) PAGE NO. 61 Question 1: What is a tissue? Answer: Tissue is a group of cells that are similar in structure and are organised together to perform a specific task. Question 2: What is the utility of tissues in multi-cellular organisms? Answer: In unicellular organisms, a single cell performs all the basic functions such as respiration, movement, excretion, digestion, etc. But in multicellular organisms, cells are grouped to form tissues. These tissues are specialised to carry out a particular function at a definite place in the body. For example, the muscle cells form muscular tissues which helps in movement, nerve cells form the nervous tissue which helps in transmission of messages. This is known as division of labour in multicellular organisms. It is because...

NCERT In Text Questions Page No: 69 1. What is a tissue? Answer Tissue is a group of cells that are similar in structure and are organised together to perform a specific task. 2. What is the utility of tissues in multi-cellular organisms? Answer In multicellular organisms, the different types of tissues perform different functions. Since a particular group of cells carry out only a particular function, they do it very efficiently. So, multicellular organisms possess a definite division of labour.

Answer: A group of cells that are similar in structure and work together to achieve a particular function is called tissue. Question 2. What is the utility of tisues in multi-cellular organisms ? Answer: In multicellular organisms division of labour is due to presence of tissues. Each tissue performs a specific function efficiently. Page 72 Question 1. Think about which gas may be required for photosynthesis? Answer: Carbon dioxide (CO 2) gas. Question 2. Find out the role of transpiration in plants. Answer: Eoles / functions of transpiration : • It is due to this that water and mineral from roots reach leaves and other parts of the plants. • It helps in the ripening of crops and fruits. • It helps in maintaining humidity which keeps the surrounding tempera-ture low.

As far as cells are concerned, we have studied that cells are structural and functional units of life. The cells, when formed, undergo the process of differentiation according to the functions that they will perform. The cells that have the same structure, features and perform the same functions form a particular type of tissue. Let us start with the chapter where we will learn all about it. The cells which are specialized in a function are grouped together and form a particular type of tissue. We have different tissues in our body that performs different functions like : • They play the role of protection. • They help in control and coordination. • They help in transportation. • They act as insulators. • Many more functions are performed. Let us learn about Plant tissue Top Types of plant tissues They are classified into mainly two types as given below • Meristematic tissue • Permanent tissue Top Meristematic tissue and its types You all have seen that plants have a tendency to grow and keep growing throughout their life. This is because of certain cells in it that keep on dividing and they are called meristematic cells. Let us learn about them. They are formed of cells that have the ability to divide continuously throughout their life and help in increasing the length and girth of the plant. Characteristics of meristematic cells • They have thin cellulose cell walls. • The meristematic cells may be spherical, oval, polygonal or rectangular in shape. The meristermatic cel...

Tissues are mainly classified into two types: 1.Plant Tissues 2. Animal Tissues 1.Plant tissues → Plants do not move, i.e., they are stationary. → Most of the tissues they have are supportive, which provides them with structural strength. → Most of these tissues are dead, as they can provide better mechanical strength than the live ones, and need less maintenance. → Some of the plant tissues keep on dividing throughout the plant life. These tissues are localised in certain regions. Types of Plant Tissues: Based on the dividing capacity of the tissues, various plant tissues can be classified as growing or meristematic tissue and permanent tissue which have further s...
