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.
Onion cells do not contain chloroplasts because onions are not photosynthetic organisms. Chloroplasts are only found in plant cells that require photosynthesis to produce energy for the cell. Onions obtain their energy through other metabolic processes and do not need chloroplasts for this purpose.
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.
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.
No, you cannot observe chloroplasts in onion cells because onion cells do not contain chloroplasts. Onions belong to a group of plants known as monocots, which typically lack chloroplasts in their cells. Chloroplasts are mostly found in the cells of green plants that undergo photosynthesis.
Onions are the root bulbs of onion plants. The plant itself contains chloroplasts, which cause the green colour, whereas the onion bulb itself contains other pigments and few, if any, chloroplasts.
The bulb of the onion does not but the leaves of the onion plant do.
Onions are underground structures. They do not get sunlight.

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 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.
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.
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.

No
i think it's because onions grow underground so chloroplasts are not needed to absorb sunlight.
