• Part (a) carries ~2 marks (½ mark each function) and part (b) carries ~1 mark (½ each).
• Keep each function to one crisp line — examiners deduct for vague answers like "helps in reproduction."
• For (b), the key contrast is: sperm is motile (has a tail/flagellum) while the egg is non-motile but large and rich in stored food (yolk). This distinction is a common exam point.
