BIOL 1202 Study Guide - Final Guide: Cotyledon, Dicotyledon, Monocotyledon
Document Summary
Plant sex: other mechanisms used by bisexual flowers to avoid self-fertilization, genetic self-incompatibility, gauged by s-genes, (50-60 alleles, diploid plant gets 2 alleles) 3 parts of plant embryo: hypocotyl (root, epicotyl (shoot, cotyledon (seed leaves; dicots have 2, monocots have 1) Chapter 35 (and 36 & 37: flowering plants: 2 main groups, monocots: seedlings have each 1 cotyledon (seed leaf, eudicots (dicots): seedlings each have 2 cotyledons (seed leaves) Breathing roots conduct oxygen to waterlogged roots: epiphytes are organisms that grow on the outside of other organisms, the roots of many orchids are photosynthetic. Leaves: know the leaves in figure 35. 6, simple leaf (dicot), compound leaf, and doubly compound leaf, some arid-adapted plants have succulent leaves. Leaves specialized into spines help defend against herbivores. Leaves specialized to trap animals occur in carnivorous plants: found in bogs in the carolinas. Leaf hairs (trichomes; know for exam) help reduce water loss and provide some protection against herbivores.
