Hey Guys,
So I'm getting a bit confused on the alternation of generations in plants. I understand that plants undergo an alternation of generations between the haploid gametophyte stage and diploid sporophyte stage, and nonvascular plants (bryophtes) are most dominant in the haploid gametophyte stage.
What I don't understand is how does this relate to the male/female gametophytes, meaning the pollen and stigma. For instance... angiosperms are dominant as the sporophyte generation but produces the male gametophyte pollen...
Are there two separate gametophytes/sporophytes in plants? One indicating reproductive anatomy and the other the actual stage of the plant?
