Question

Describe the trends that you see in the evolution of land plants in terms of: gametophyte or sporophyte dominance size and independence (whether or not it can live on its own) of the gametophyte or sporophyte Make sure that you identify those two traits for each of the major land plant groups : 1) "Bryophytes" 2) Ferns and Lycophytes 3) Seed Plants (Gymnosperms and Angiosperms) New piece of information: diploid organisms have higher survival under high ultraviolet radiation environments (i.e. on LAND!) than haploid organisms. Using the trends you observed and the new information above, make an inference: WHY do we observe these trends in the land plants? (In other words, how might higher survival of diploid organisms under high UV conditions explain the trend you observe.)

Answer 1

Explanation below.

Step-by-step explanation:

Gametophytes are plants that reproduce not by spores but by gametes, that is male and female gametes.

Sporophytes are the plants that make use of spores as the means of reproduction. This means that they produce spores.

1. Bryophytes are sporophytes

2. Fern or lycophytes are sporophytes

3. Seed plants are gametophytes. And that is why they possess both male and female gametes.
