      What is the general pattern of alteration of generations for algae and plants?

      I wasn’t aware that algae did it, and only some plants really do it.

      Wrong forum. Try the botany forum. But this is how it generally works. In the Bryophtyes (Mosses) the gametophyte generation is dominant and the sporophyte generation grows out of the top. In the rest the Pterophytes (ferns), gynmosperms (conifers), and angioperms (flowering plants) the sporophyte is dominant and then the gametophyte stage. Thats for plants.

      The problem is that for the higher plants, the sporophyte stage ceases to be an asexuallly reproducing stage (for the most part). So alternation of generations as a group characteristic isn’t present.
