Question

Consider the following statements and select the correct option:

(A) Intercalary meristems occur in grasses.

(B) Apical meristems and intercalary meristem are primary meristems.

(C) Fascicular cambium, interfascicular cambium, cork cambium are examples of lateral meristems

(D) In a young dicot root, cambium is absent.

• A. All the above statements are correct
• B. All the above statements are wrong
• C. Statements a and b are correct, c and d are wrong
• D. Statements c and d are correct, a and b are wrong

Answer 1

The correct option is A

All the above statements are correct

Intercalary meristem are found in grass and are responsible for the formation of leaf primordia.
Primary meristem, along with the Promeristem is responsible for the primary growth of plant and is found in the Apical and intercalary region.
Lateral meristem is mostly responsible for the increase in girth of the plant. Thus Fascicular cambium, interfascicular cambium and cork cambium are types of lateral meristem.
The young dicot root has parenchymatous tissue called as conjunctive tissue. This tissue reverts back to meristematic state and becomes the cambium once the root matures.
