Spermatogenesis uses meiosis.
The embryo embeds in the uterine wall.
Progesterone keeps the uterine lining.
One sperm forms the zygote, the other forms endosperm.
The ovary wall becomes the fruit.
Pollen grains carry the male gametes.
The epididymis stores and matures sperm.
Nutrients and oxygen pass to the foetus.
