Question

Throughout the evolution of the land plants, the sporophyte generation has become _______ and more independent of the gametophyte, and the gametophyte generation has become _______ and more dependent on the sporophyte.

A. larger; smaller
B. larger; larger
C. larger or smaller; larger
D. smaller; smaller
E. smaller; larger

Answer 1

A. larger; smaller

Step-by-step explanation:

The life cycle of plants is divided into two phases that is the sporophyte and the gametophyte.

In non-vascular plants, the gametophyte generation remains dominant and larger in size compared to the sporophyte but during the evolution of the plants from the non-vascular to vascular plants the gametophyte generation size has reduced while the sporophyte generation has become very large compared to the gametophyte.

Thus, Option-A is the correct answer.
