D) Dermatogen
Show Answer
Answer:
Correct Answer: C
Solution:
Intercalary meristem is the meristems present at the base of the internodes of stem or leaf.
These are derived from the residual apical meristem, traces of which were left at the nodes and internodes of the stem or leaf.
It helps in the elongation and growth of the plants at the nodes and internodes (stems and leaves) and also enables the longitudinal growth of the stem and leaves in grasses.
Intercalary meristems which are present at the nodes of hollow stems or culm (in sugarcane and bamboo) allows rapid stem elongation whereas, those present at the base of leaf blades in grasses allow damaged leaves to rapidly regrow
So, the correct answer is ‘Intercalary meristem’
