because onions are grown underground, where as underground have no sunlight. And the function of chloroplast is to trap light energy for plants to make food.

Why are onions and humans used as the source of cells?
what is chloroplasts
Why the chloroplasts is not present in the onion cell?
You can't see chloroplasts in an onion skin cell since the onion was underground. When the onion is underground, the sun can't reach the onion so the onion skin cells can't make glucose. The onion does have chloroplasts in its cells at the top of the onion. That's where he sunlight can reach the onion.
Do onions have choroplasts do elodea plants carry out photosynthesis?
Just did this lab in Biology. Onion cells do not have chloroplasts; therefore, they do not possess the green pigment, chlorophyll, that chloroplasts produce. Elodea plants do carry out photosynthesis.
How do potato cells differ from onion cells?
No, Onion cells does not contain chloroplast
Why are chloroplasts not ordinarily visible in an unstained onion cell?
1. Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground

what is chloroplasts
Why are no chloroplasts fond in the onion cells?
Onions are underground structures. They do not get sunlight.
Do onions have chloroplasts in their cells?
The bulb of the onion does not but the leaves of the onion plant do.
Do onions have chlorplast?
No,due to the onion have to be underground.Which means why does it need chloroplasts if its underground.The onion has not green in it anyways.
Why aren't onions green?
why aren't onions green Because onion bulbs are produced underground as storage of food. Being away from sunlight, the onion scales lack chloroplasts ( the green color pigment ) hence onions are not green.
Why do onions have gucose not starch?
because it is technically a Leaf! its chloroplasts are white because it is underground..its roots are under the onion! the onion is NOT a root, so no starch only the monosaccharide glucose from the chloroplasts.

Do onions cell have chloroplasts?
No
How do potato cells differ from onion cells?
No, Onion cells does not contain chloroplast
Why aren't there any chlorplasts in onion cells?
i think it's because onions grow underground so chloroplasts are not needed to absorb sunlight.
What plant cell structures appears to be missing from the cells of an onion bulb?
I think that it is chloroplasts because chloroplasts contain chlorophyll and need light to work and since onions are grown underground they do not need light to grow. I am not 100% sure but I think that it makes sense.
