Document Summary
Has many species in it that are photosynthetic. Red algae, green algae (ancestors of modern land plants) They alternate between two multi cell stages, Moss- haploid multi cell organism, each cell. Sporocytes (2n) meiosis to produce spores (n) All plants produce spores, those spores are. Waxy covering on the top and a little on the bottom, protects against sun damage, scratches, parasites from coming in: 6. Little holes, mouths, opened and closed by cells. This is where gas exchange to take place. Get rid of excess oxygen, get more carbon. Lose water when mouths are open too. Open mouths to get water too: 1. 2 bya first microorganisms on land dioxide. Before this all photosynthesis was taking place. Non-vascular plants: e. origin and diversificartion of plants, bryophytes (grade, mosses, cannot get very tall, have. Bryophytes: includes mosses, three phyla of small herbaceous plants (small, have no wood, fluffy tissue) Liverworts (phylum hepatophyta: mosses (plylum brophyta, hornworts (phylum anthocerophyta)
