BI111 Chapter Notes - Chapter 35.3/29.1: Vascular Cambium, Dicotyledon, Monocotyledon
Document Summary
Evolution of gymnosperms created more food for animals, insects, birds, and mammals. Angiosperms may have originated in the shady understory of the tropical forest: Plants enlist animals to help them redrocide. Vines and shrubs are two examples of growth forms exhibited nu early diverging. The movement of animals from one flower to another created pollen transfer angiosperms. Angiosperm diversity result from flower and xylem vessels among other traits as well as coevolutionary interactions with animals and other organisms; Monocot has the vascular bundles spread throughout. Dicot is the same as the unicot. Angiosperms are more efficient at building their bodies and completing their life cycle than other plants. The diversity of shapes and sizes of angiosperm reduces competition. Monocots are diverse in shape and size despite not forming vascular cambium: Make up one quarter of all angiosperms. Most important group of plants for what we eat. Have poor fossil record because they do not produce wood.
