BIOL 1202 : Bio 2 Test 2 Notes
Document Summary
Phylogeny and the tree of life: phylogeny, the evolutionary history of a species or group of related species, systematics, an analytical approach to understanding the diversity and relationships of organisms. Concept 27. 4: molecular systematics is illuminating prokaryotic phylogeny: a tentative phylogeny of some of the major taxa of prokaryotes based on molecular systematics. Chapter 29: plant diversity 1; how plants colonized land. Concept 29. 3: ferns and other seedless vascular plants were the first plants to grow tall: life cycles with dominant sporophytes: sporophytes of seedless vascular plants are the larger generation. The gametophytes are tiny plants that grow on or below the soil surface: classification of seedless vascular plants, two phyla, lycophyta: club mosses, spike mosses, and quillworts, pterophyta: ferns, horsetails, and whisk ferns. Increases surface area for capturing more sunlight: significance of seedless vascular plants, ancestors of modern lycophytes, horsetails, and ferns formed the first forests during the carboniferous (359-299 mya, decayed and became coal.
