Gametes and fertilisation

HideShow resource information
Name the two gametes
Sperm cells and egg cells
1 of 6
Number of chromosomes contained by both gametes
23
2 of 6
Describe and explain the structure of the sperm cell
Acrosome enzymes to digest the zona pellucida; midpiece contains ATP to provide energy for movement; flagellum allows the sperm to swim to egg
3 of 6
Describe and explain the structure of the egg cell
Zona pellucida contains glycoprotein layer to protect the egg; follicle cells
4 of 6
Describe the acrosome reaction
Release of digestive enzymes from the acrosome; digestion of zona pellucida; fusion of sperm with egg cell membrane; egg releases cortical granules
5 of 6
Suggest how smoking affects male fertility
Decrease in sperm motility; poor movement prevents fertilisation; damage to DNA
