Diagram the following inflorescence types: spike, raceme, panicle, corymb, umbel, composite head. Distinguish between complete and incomplete flowers; perfect and imperfect flowers. What does the term monoecious mean when referring to a flowering plant? Explain other ways that flowers may vary by defining the terms connation, adnation, epigynous, hypogynous and perigynous. Describe the characteristics of flowers that are pollinated by wind; bees, moths, hummingbirds, and bats.

17. Draw a diagram to represent the life cycle of a flowering plant. Make separate lines to distinguish microsporogenesis and microgametogenesis from megasporogenesis and megagametogenesis. Explain the difference between pollination and fertilization. What is double fertilization. label the parts of the megagametophyte. Which cells will become the endosperm and the embryo?
