The layers of an onion are essentially onion leaves. However, Onions are grown underground and get no sunlight, hence no chlorphyll development which equals white.

Only the bulb of the onion is white, and for most it is only the inside of the bulb. The outer skin is yellow or red. The above ground part is green when growing. It is that whole photosynthesis thing. Get some extra credit and ask your teacher why some yellow onions are yellow all the way through!

I think the question should be why do onions come in different colors like White, Red and Yellow?

because they were born that way, haha, actually, there are some that are red/purple and yellow too and then some called green onions with the root part mostly white but sometimes with green layers too.

Because of the pigment contained in the skin of the onion.

Onions aren't all white. Some are yellowish, and others are kind of purple.

they can potentially be green. The base of an onion plant is the actual onion. it doesnt get green because It doesnt get any sunlight.
