Answer 1

Correct choice is (d) Pith in a dicot root quite larger than that of a mono cot root

Explanation: The layer just inside the endodermis in a dicot root is called pericycle. The portion between endodermis and epidermis is covered by parenchyma cells. Secondary growth initiates from the cells of pericycle. Pith in a mono cot root is quite larger than that of a dicot root.
