Gametes = sex cells
Gametes are the sex cells that fuse together during fertilisation in sexual reproduction. Female gametes may be called ova or eggs. Male gametes are sperm or pollen.
A sperm whale and an egg take on a goat at a game of cards. They love gambling and place an opening gambit (gamete).
The whale has pulled on (pollen) mitts and the egg is oval (ova) shaped.
