Which of These is a Major Trend in Land Plant

Question

Which of these is a major trend in land plant evolution?
A) the trend toward larger gametophytes
B) the trend toward a sporophyte- dominated life cycle
C) the trend toward a gametophyte- dominated life cycle
D) the trend toward smaller size

Accepted Answer

The trend toward a sporophyte-dominated life cycle is a major trend in land plant evolution, as seen in the progressive reduction of the gametophyte generation and the increasing complexity and independence of the sporophyte generation. Therefore, option B is the correct answer. Options A, C, and D are not major trends in land plant evolution.
