BIOL 1002 Study Guide - Final Guide: Venus Flytrap, Leaf, Apical Dominance
Document Summary
Monocot seedlings each have 1 cotyledon use fibrous root system. Dicot seedlings each have 2 cotyledon use taproot system. Root hairs extensions of epidermal cells dramatically increase roots surface area for absorbing water and nutrients. Food storage is a function of all roots, but some are highly modified for o storage o o o. Support branches, flowers (which become fruits), leaves, etc. Tubers (eg. potatoes, yams) are the swollen ends of rhizomes, o o o specialized for food storage o bases of leaves specialized to store food o (particularly mammalian browsers) Bulbs are vertical, underground stems consisting mostly of the swollen. Thorns are rigid, sharp branches that deter potential herbivores. Terminal bud exercise apical dominance over axillary buds activate and form branches. The terminal (top) bud will grow before the lower buds. Trimming the terminal bud will cause the next buds down to. Compound leaf has leaflets petiole is the stalk attaching the leaf blade to the stem.
