Be familiar with the following: the phylum (division) that contains the angiosperms (Angiospermae) the two classes within the phylum (Monocotyledones and Dicotyledones the characteristics of plants within each class (Figure 31.5) the vegetative organs and parts of the plant body leaves stems branches roots stems and leaves together form the shoot system nodes form where leaves attach to stems internodes are the areas between the nodes roots form the root system many dicots have a taproot system monocots and some dicots have a fibrous root system root apical meristems at the tips of roots and is the primary growth region, it is protected by a root cap adventitious roots arise from the stem near the ground and provide additional support for the plant lateral buds at nodes on the stem may develop into branches at a later time stems may be highly modified a potato is a modified stem called a tuber strawberry plants have runners that can put down roots and become separate plants shoot apical meristem is found in the apical bud of the stem and serves as a primary growth region for the stem although leaves are the primary areas of photosynthesis, stems often contain chloroplasts and are photosynthetic leaf primordia produced by the shoot apical meristem will give rise to the leaves leaves are important in photosynthesis;
