Question

Grass stem elongates after initial growth due to

• A. Apical meristem
• B. Secondary meristem
• C. Intercalary meristem
• D. Lateral meristem

Answer 1

The correct option is C Intercalary meristem

In angiosperms, intercalary meristems occur only in monocot in particular, grass stems at the base of nodes and leaf blades.

Intercalary meristems are capable of cell division and they allow for rapid growth and regrowth of many monocots. Intercalary meristems at the nodes of bamboo allow for rapid stem elongation, while those at the base of most grass leaf blades allow damaged leaves to rapidly regrow

So, the correct answer is 'Intercalary meristem'
