How do sperm and eggs differ in size? (consider size and the quatity of each gamete). Explain possible reasons for these differences.

Answer 1

Eggs are much larger than sperm.

Answer 2

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.
