CAIE IGCSE Biology 16.4.4 Adaptive features of sperm
Practise explaining sperm adaptations from diagrams, tables and photomicrographs, linking structures to movement and egg penetration.
How this is tested
- link flagellum and mitochondria to movement towards the egg
- explain how acrosome enzymes digest the egg jelly coat
- interpret sperm abnormality data to decide why fertility is reduced
