Document Summary

Nonvascular: have no vessels, no roots, no stems or leaves. Vascular: have vessels to transport food and water. "naked seeds" cone bearing plants (seeds grow on cones: needle like leaves, usually stay green year round, wind pollinated, examples: pine trees & evergreens. Angiosperms flowering plants seeds are enclosed in a fruit: most are pollinated by birds & bees, have finite growing seasons, examples: grasses, tulips, oaks, dandelions, divided into two main groups: monocots & dicots. Monocots: angiosperms have have 1 seed leaf (cotyledon, parallel veins on leaves, 3 part symmetry for flowers, example: lilies, onions, corn, grasses, wheat fibrous roots. Dicots: angiosperms that have 2 seed leaves (cotyledons, net veins on leaves, examples: trees and ornamental flowers flowers have 4-5 parts taproots. Roots: water and minerals are absorbed (taproots vs fibrous roots, movement of water up to leaves is influenced by transpiration also used to anchor the plant.
