How do sperm and eggs differ in size? (consider size and the quatity of each gamete). Explain possible reasons for these differences.
Eggs are much larger than sperm.
In terms of size, think of an egg as a large spherical pizza. The sperm would be one very small meatball in that pizza.
In terms of quantity, one egg is usually ovulated each month, and there are between 100-600 million sperm in each ejaculation.
Now you think of the possible reasons.
