Document Summary

Vascular plants (with conducting tissue: non-vascular vs vascular. Seed plants: no seeds vs seeds. Radiation of flowering plants: no flowers vs flowers. Topics: flower structure (including evoluationary trends) and pollination (online videos, the angiosperm reproduction, relationship between sporophytes and gametophytes, microsporogenesis, microgametogenesis, megasporogenesis, megagametogensis, embryo development, asexual development, evolution of the flower. List and give examples of 3 classes of anthophyta. Describe some refinements in vascular tissue that occurred during angiosperm evolution. Explain how evolution of the flower enhanced the reproductive efficiency of angiosperms. Identify the floral structures and describe the function of each. Describe four commonly recognized evolutionary trends in floral structure found in various angiosperm lineages. Define fruit and explain how fruits are modified in ways that help disperse seeds. Diagram a generalized life cycle of an angiosperm, identify the haploid and diploid structures and explain how it differ from the life cycle of a pine.
