Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont need chloroplasts, so they dont have them.

∙ 12y agoYou can simply tell that there is no chloroplast in onion bulbs because they are not green. Onion bulbs just basically shares a similar environment with root cells.You can check the images in Google and you actually see that onion cell does not have any chloroplasts.

∙ 14y agothey don't because they have onion bulbs which do the work that the chloroplast does

How do potato cells differ from onion cells?
No, Onion cells does not contain chloroplast
Why don't onion cells contain the function of a chloroplast?
The onion is a part of the root, which is usually underground. Thus, it has no need for chloroplasts to photosynthesize.
Why do onion cells do not have chloroplast?
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
What cells have chloroplast?
The chloroplast, an organelle, is found on plant cells and other eukaryotics organism that conducts photosynthesis.(they aren't in sperm cells)
Do muscle cells have chloroplast?
Only plant cells contain chloroplasts.

Do the onion scale leaf cells contain chloroplast?
No. Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form.
What structure can be seen in Elodea leaf but not present in epidermal cells of onion cells?
Chloroplasts, because the onion does not undergo photosynthesis. The onion plant does but the onion itself is a bulb.
What part of the onion would have chloroplast?
All plant cells contain chloroplasts, the amount present depends on the function of the cell. for example leaves will contain loads of chloroplast, hence why they are green. The cells of an onion will still contain chloroplasts but only a few in comparison to the amount in a cell situated in the leaf. This is because onions are underground and aren't the primary site for photosynthesis.
Is the chloroplast in onion cells larger than the nuclei?
Chloroplasts are larger than nuclei. A typical Chloroplast measure 4 to 6 um, and a typical nucleus measure about 3 um.
Why do onion cells do not have chloroplast?
Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
What cell chloroplast?
Plant cells contain the Chloroplast type organelle.
What units contain chlorophyll?
Plant cells that contain chloroplast.
Does a animal contain chloroplasts?
Animal cells do not contain chloroplast, only plant cells.
Why is a chloroplast important for plant cells?
Chloroplast contain chlorophyll which is important for plants for making food that's why chloroplast is important for plant cells.
What cells have chloroplast?
The chloroplast, an organelle, is found on plant cells and other eukaryotics organism that conducts photosynthesis.(they aren't in sperm cells)
