Document Summary

2/10/17 domain eukarya: true nucleus/endomembranes supergroup: unikonta flagellated cells subgroup opisthokonta flagellated cells (sister is choanoflagellate) kingdom animalia internal digestion (heterotroph) phylum chordate nerve cord class mammal (milk) eutharian order primate (thumbs) species homo sapiens. Archaeplastida: monophyletic clade: characteristics of land plants, evolution of land plants. Characteristics of charophytes that enabled move to land. Algae and plants share some traits: derived traits of land plants. Seven derived traits of land plants: alternation of generations. Spores (n) by meiosis: multicellular dependent embryos, walled spores produced in sporangia, multicellular gametangia produce gametes, apical meristems, cuticle, stomata (singular = stoma) Classification of land plants: flagellated sperm similar in both, phragmoplast scaffold for cell plate assembly. Sporocytes (2n) -> meiosis to produce spores (n) Desiccation = drying out: rings of cellulose-synthesizing proteins-make microfibrils of cell walls. 470 mya fossils of spores from land plants. Tied water (like amphibians of the plant kingdom: vascular plants. Three phyla of small non-vascular herbaceous plants: bryophyte life cycle.
