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 smaller size
B)the trend toward a gametophyte-dominated life cycle
C)the trend toward a sporophyte-dominated life cycle
D)the trend toward larger gametophytes

Accepted Answer

The trend in land plant evolution is toward a sporophyte-dominated life cycle, where the diploid sporophyte generation becomes larger and more complex, while the haploid gametophyte generation becomes smaller and less complex. This is evident in the evolution of seed plants, where the gametophyte generation is reduced to just a few cells and is dependent on the sporophyte generation for nutrition.
