1
Q
What happens during fertilsation 1/4
A
Enzymes in acrosome of sperm head digest zona pellucida
2
Q
What happens during fertilsation 2/4
A
Sperm head fuses with ovum cell membrane, allowing sperm nucleus to enter
3
Q
What happens during fertilsation 3/4
A
Cortical reaction causes zona pellicida to harden preventing polyspemry
4
Q
What happens during fertilisation 4/4
