How many of the following statements are correct with respect to embryogeny?
I. In monocots, the basal cell is smaller and lies towards the chalazal end.
II. In dicots, the terminal cell contributes to the formation of a suspensor.
III. In monocots, the basal cell doesn’t divide and transforms directly into a large vesicular cell.
IV. In dicots, the hypophysis gives rise to the embryonic root and root cap in the embryo.

The correct option is B 2
The early stages of embryo development are similar in both monocots and dicots.
The zygote divides transversely to form the terminal cell and the basal cell.
The terminal cell, by subsequent divisions, gives rise to the embryo, while the basal cell contributes to the formation of the suspensor in dicots.
In monocots, the basal cell is larger and lies towards the micropylar end. It doesn’t divide again and becomes transformed directly into a large vesicular cell.
(16C12B02C027) In dicots, the part of the embryo at the tip of the suspensor is called hypophysis. It gives rise to the embryonic root and root cap in the embryo.
So, here we can say that statements III and IV are correct. Statements I and II are incorrect.
