Presentation on theme: "Seeds and Fruits. Alternation of Generations All plants have a life cycle in which a diploid sporophyte generation alternates with a haploid gametophyte."— Presentation transcript:
Seed Development Hypocotyl – embryo attaches to cotyledons. Radicle – embryonic root Epicotyl – will develop into stem. Plumule – develops into first leaves. Scutellum – absorbs nutrients during germination. Coleorhiza – sheath that covers young root. Coleoptile – covers shoot
Plant Propagation & Agriculture Vegetative reproduction includes the production of new plants from horizontal stems, cuttings, leaves, plantlets, and underground roots. Horticulturists use plant propagation to make many identical copies of a plant or to produce offspring from seedless plants. Most of the people of the world depend on a few crop plants, such as wheat, rice, and corn, for the bulk of their food supply. Peanut Flower
