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.

Onions do not contain chloroplasts because they do not perform photosynthesis. Instead, onions rely on obtaining nutrients from the soil to grow and sustain themselves. chloroplasts are found in plant cells that undergo photosynthesis to produce energy for the plant.

Why don't onion cells contain the function of a chloroplast?
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.
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.
Can you observe any chloroplast in the onion cell using microscope?
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.
Do the cells of the onion bulb possess chloroplasts?
No, the cells of an onion bulb do not contain chloroplasts. Onions belong to the group of plants that store energy as carbohydrates in their bulb. Chloroplasts are predominantly found in green plant tissues where photosynthesis occurs.
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.
What plant cell structures appears to be missing from the cells of an onion bulb?
Chloroplasts appear to be missing from the cells of an onion bulb, as onions are generally grown for their underground bulbs and not for photosynthesis. Onions rely on the stored energy in their bulbs for growth and reproduction, rather than producing their own energy through photosynthesis.

Do onions cell have chloroplasts?
No
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.
Can you observe any chloroplast in the onion cell using microscope?
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.
