Do mosses have an alteration of isomorphIC Or heteromorphic generations? That is, can you easily tell a moss gametophyte from a moss sporophyte? When we look at leafy green moss plants, what are we seeing - gametophyte or the sporophyte? in a fiowering plant species, would the equivalent stage be the plant the pollen grains and megagametophytes

What is the position of the sporangia (describe specific position/orientation of sporangia on the stem or leaf blade) of the following plant groups: a. Bryophytes b. Rhyniophytes c. Lycophytes d. Monilophytes
Trimerophytes were plants that probably evolved from rhyniophytes but with more derived features. In one feature, certain stems grow longer than others, and thus, rather than having dichotomous branching, they have branching (displayed especially by Pertica). Simultaneously, the positioning of branches became more and .
