BIOL 201 Study Guide - Final Guide: Cork Cambium, Sporangium, Lycopodiopsida
Document Summary
Biology 201 final review: aarssen lectures 1-12 + grogan fungus lectures. Origin, evolution and classification of land plants. The link between life and non-life, photosynthesis: the conversion of light energy and fixation of carbon, chemical energy, carbon skeletons, oxygen. Simple design of photosynthesis machines, mitosis to grow laterally across soil: minimized wind exposure, maximized water absorption and light uptake. Spongiophyton: no vascular tissue, all surface cells are photosynthetic , pores to uptake co2. Mutation: genes are subject to random change; beneficial mutations will remain in a population and begin speciation. Meristems: where mutations accumulate because it is the site of genetic processes: consists of undifferentiated cells, the way plants have evolved certain phenotypes is dependent on meristem function. Mutation variation natural selection evolution organic diversity. Acquiring genetic variability: the role of sex. Since the environment is not homogeneous, it only makes sense that there is a mixture of genetic types.
