Question

Assertion : Intercalary meristem increase length of plant like apical meristems.
Reason : Intercalary meritem originates from the apical meristems.
A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
C. If Assertion is true, but Reason is false.
D. If Assertion is false, but Reason is true.

Answer 1

Correct Answer - A
Intercalary meristems are intercalated in between the permanent tissues. The activities of this 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 gasses when the internodes complete their elongation, some cells ate the base retain their meristematic activity and function as intercalary meristems. They lie just above the node.
