Assertion : Intercalary meristem increase length of plant like apical meristems.
Reason : Intercalary meritem originates from the apical meristems.

Options

B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false

Answer

A

Explanation

Intercalary meristem are intercalated in-between the permanent tissues. The activities of these meristems also add to the length of the plant or its organs. They originate from the apical meristems when their portions get detached due to the growth of the organs. For example, in the grasses when the internodes complete their elongation, some cells at the base retain their meristematic activity and function as intercalary meristem. They lie just above the node.
