O Diploid, Haploid O Triploid, Diploid O Haploid, Diploid O Diploid, Triploid
- What is microsporophyll of angiosperm called?Do mosses have an alteration of isomorphIC Or heteromorphic generations? That is, can youeasily tell a moss gametophyte from a moss sporophyte? When we look at leafy green mossplants, what are we seeing - gametophyte or the sporophyte? in a fiowering plant species,would the equivalent stage be the plant the pollen grains and megagametophytesWould you expect the sporophyte generation of a moss or a fern to have more mitotic divisions? Why?
