In the following questions, two statements are given- one labelled

     Assertion(A) and the other labelled Reason (R). Select the most appropriate  

     answer from the options given below:

Assertion: Simple tissue is made up of only one type of cell.

 Reason: All the simple tissues in plants are permanent that have lost the 

                capacity to divide.

• Both (A) and (R) are true, and (R) is the correct explanation of the (A)

• Both (A) and (R) are true, but (R) is not the correct explanation of the (A).

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Assertion: Apical meristem is present in root and shoot apices

       Reason: Apical meristem helps in longitudinal and internodal growth of

       plants.
