The nutritive material or yolk stored in an egg that provides food for the developing embryo.
From Greek 'deuteros' (second) + 'plasma' (something molded or formed), literally meaning 'secondary substance.' It refers to secondary substance in the egg as opposed to the protoplasm of the nucleus.
Your egg yolk isn't just delicious to eat—it's deutoplasm, the packed lunch that growing baby birds, fish, and other creatures eat while developing inside the egg before they're born!
