Non-Gender Parts: petals sepal

from the anther to the stigma Pollination: the transfer of pollen stigma of the same flower or plant one flower is transferred to the 1. self-pollination – the pollen of (offspring will be genetically identical)

stigma of another plant one flower is transferred to the 2. cross pollination – the pollen of (offspring will be genetically different)

Double Fertilization: the ovary stigma, it grows down the style to 1. when the pollen lands on the 2. each pollen grain has two sperm form the zygote (aka: the seed) a. one sperm fuses with the egg to

Double Fertilization: (a source of nutrition for the zygote) rest of the ovary to form the fruit b. the other sperm fuses with the

Dispersal of Seeds: 1. wind 2. water 3. animals a. stick to their fur not digested b. fruit is eaten but the seeds are
