Document Summary

Two major groups of angiosperms: dicots and monocots. Root system: tap root vs. fibrous root. Roots below the ground are equal to the amount of leaves above the ground. Modifications of stem, leaf and root for food storage, propagation and defense and mechanical support. (example: a potato grows tuber modified stems to create more potato plants) 2two major groups of angiosperms: dicots and monocotspay attention to:root system: tap root vs. fibrous root. leaf base: petiole vs. sheathleaf venation: reticulate vs. parallel4the dermal tissue system is the outer covering of the plant. The ground tissue system carries out photosynthesis, stores photosynthetic products and helps support leaves. The vascular tissue system conducts water and solutes throughout the plant. Girth (diameter) of plant increased by secondary growth. Increase in plant height by primary group of the meristem. In a cross-section of the stem, vascular bundles are arranged differently in dicots (in a ring) and monocots (scattered).
