 NCERT Class 9 Science Chapter 6 Tissues Questions- Answers

 Intext Questions

Class 9 ch 6 questions answer Page No. 69

Q.1  What is a tissue?

Ans. Tissue is a group of related cells that have a common origin and perform a common function.


Q.2  What is the utility of tissues in multi-cellular organisms?

Ans. In multi-cellular organisms, the different types of tissues perform different functions. Since a particular group of cells called tissue performs a particular function, they do it very efficiently. Thus, multi-cellular organisms possess a definite division of labour. tissues provide structural strength, mechanical strength, and division of labour.
