Examples of Incomplete Flowers: Recognize perfect vs. imperfect. if imperfect a monoecious plant vs a dioecious one.
Begonia: an imperfect flower; both sexes are found on the same tree, hence is monoecious.
Oak: an imperfect flower; both sexes are found on the same tree, hence is monoecious.
Box Elder: an imperfect flower; sexes are found on different trees, hence is dioecious.

Lilium Life Cycle:Recognize the ovary, carpels, ovules, integuments, nucellus (megasporangium), megaspore mother cell, anther, tapedum, pollen grains (microgametophytes), four and eight-celled embryo sacs (megagametophytes), and, in double fertilization, the two sperm nuclei ans each karyogamy event - one resulting in a diploid zygote, the other in the formation of a primary endosperm nucleus).
Fruits: Recognize each fruit type and how each is adaptive.
