Pollen that contains sperm cells are released from the male anther (part of the stamen).
Pollen grains stick to the stigma (the top of the female pistil).
Sperm cells travel down the pollen tubes and fuse with female ovules; these create zygotes, or new genetic identities.
The ovule turns into a seed, the ovary turns into a fruit around it.
Pollen tubes grow to take the pollen down to the ovary.
