CAS BI 108 Chapter Notes - Chapter 38: Seed Dormancy, Pollen Tube, Cotyledon
Document Summary
Angiosperm flowers can attract pollinators using visual cues and volatile chemicals. Symbiotic relationships are common between plants and other species. Since the beginning of agriculture, plant breeders have genetically manipulated traits of wild angiosperm species by artificial selection. 38. 1 flowers, double fertilization, and fruits are key features of the angiosperm life cycle. Identify and describe the function of a sepal, petal, stamen (filament and anther), carpet (style, ovary, ovule, and stigma), seed coat, hypocotyl, radicle, epicotyl, endosperm, and cotyledon. Describe the fate and function of the ovule, ovary, and endosperm after fertilization. In angiosperms, the sporophyte is the dominant generation, the large plant that we see. The gametophytes are reduced in size and depend on the sporophyte for nutrients. The angiosperm life cycle is characterized by three fs : flowers, double fertilization, and fruits. Flowers are the reproductive shoots of the angiosperm sporophyte. They attach to a part of the stem called the receptacle.
