Q. Compared with the gametophytes of the bryophytes the gametophytes of vascular plants tend to be
A) Smaller and to have smaller sex organs
B) Smaller but to have larger sex organs
C) Larger but to have smaller sex organs
D) Larger and to have larger sex organs
Explanation
[Solution from source] Moving from bryophytes to vascular plants, the gametophyte becomes progressively reduced while the sporophyte becomes dominant. The fern prothallus is small and short-lived, and in seed plants the gametophyte is just a few cells, with sex organs reduced or absent. So both the gametophyte and its sex organs become smaller. Answer (1).
