Question

The length of different internodes in a culm of sugarcane is variable because of:-

• A. size of leaf lamina at the node below each
  internode
• B. intercalary meristem
• C. shoot apical meristem
• D. position of axillary buds

Answer 1

The correct option is B intercalary meristem

Intercalary meristems are capable of cell division, and they allow for rapid growth and regrowth of many monocots. Intercalary meristem occurs at the base of the internodes or at the base of nodes or leaf. Their main function is to provide elongation and growth of that part of the plant where they are present. Intercalary meristem in plants are located in the nodes of the leaves. In sugarcane the intercalary stem is present between leaf nodes and enables longitudinal growth of the stem. Hence the length of internodes is variable

So the correct answer is 'intercalary meristem'
