Question

Intercalary meristem is derivative of

• A. Promeristem
• B. Primary meristem
• C. Lateral meristem
• D. Secondary meristem

Answer 1

Answer: (B)

Primary meristem

• Intercalary meristem is the meristems present at the base of the internodes or at the base of nodes of stem or leaf.
  
• It helps in the elongation and growth of the plants at the nodes and internodes (stems and leaves) which enables longitudinal growth of the stem and leaves (grasses).
• These are derived from the residual apical meristem which is present at the nodes and internodes.
• Since, both the apical and intercalary meristem helps in the primary growth of the plants i.e they help in cell elongation.
• Therefore, they are primary meristems.

So, the correct answer is 'Primary meristem'
