Ans.

Branches of a tree move and bend freely in high wind velocity because of the presence of collenchyma that adds the property of flexibility.

3. What is the term given to the gap between two nerve cells?     

Ans. Synapse      

4. Write true or false:

a) Amoeba is a multicellular organism.

False. Amoeba is an unicellular organism.

b) WBC can change its shape. 

True

c) The human body has cells that can perform special functions. 

True                  

8. Which among the following are made up of cells?    

Wooden table, Glass sheet, Liver, Kidney
