Document Summary

Chapter 29 plant diversity i: how plants colonized land. A second feature that unites charophyceans and land plants is the presence of peroxisome enzymes to help minimize the loss of organic products as a result of photorespiration: peroxisomes of other algae lack these enzymes. In those land plants that have flagellated sperm cells, the structure of the sperm resembles the sperm of charophyceans. Alternation of generations: multicellular embryo that is dependent on the parent plant. Sporangia that produce walled spores: gametangia that produce gametes. Bryophyte sporophytes disperse enormous numbers of spores: while the bryophyte sporophyte does have photosynthetic plastids when young, it cannot live apart from the maternal gametophyte, a bryophyte sporophyte remains attached to its maternal gametophyte throughout the sporophyte"s lifetime. If liverworts are the deepest-branching lineage of land plants, then stomata evolved once in the ancestor of hornworts, mosses and vascular plants.
