How are gametes produced?
meiosis
Where are sperm produced?
In the testes
Where are eggs produced?
In the ovaries
Sperm:
Head Nucleus (DNA) and enzyme (acrosome) which helps sperm enter egg
Middle full of mitochondria
Tail flagella to push forward
Egg:
Large round cell of cytoplasm, nucleus, and cell membrane
Jelly layer slows sperm entering egg
