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.
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.
Which part of a plant cell will you never find in a onion bulb?
As an onion cell is a cell, no cells are located in it, but maybe you mean organelles, which literally mean "tiny organs" and make up every cell. In that case, onion cells lack chloroplasts because they grow underground and therefore don't use the sun to produce energy (chloroplasts are involved in photosynthesis).
Do onion cells still have chloroplasts when they have iodine on them?
The iodine has no connection as to whether the cells have chloroplasts or not. If the cells are green, then they do have them. Adding iodine doesn't change that fact. Not all cells of the plant have chloroplasts. The ones in the soil don't so if you are working with the bulb, it doesn't have chloroplasts in the first place.
Why onion epidermal cell does not contain chloroplast?
chloroplasts contain chlorophyll which help to make the food for the plant (glucose). An onion is a bulb, it is food storage for the actual onion plant, it doesn't make its own food so doesn't need chloroplasts *Chloroplasts are used for photosynthesis (I) Hope it helps (Y)
Do onions have chloroplasts in their cells?
The bulb of the onion does not but the leaves of the onion plant do.
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 structure can be seen in Elodea leaf but not present in epidermal cells of onion cells?
Chloroplasts can be seen in Elodea leaf cells but not in the epidermal cells of onion cells. Chloroplasts are responsible for photosynthesis in plant cells, containing chlorophyll that captures sunlight for energy production. Onion epidermal cells do not contain chloroplasts as they do not perform photosynthesis.
Why the chloroplasts is not present in the onion cell?

Why are chloroplasts absent in onion epidermal cells and potato tubular cells?
Onion epidermal cells and potato tuber cells do not contain chloroplasts because they do not require photosynthesis for energy production. These cells mainly function in storage and support, so they do not need chloroplasts for the process of photosynthesis.

What plant organelle is missing from the onion cell?
The onion cell is missing chloroplasts, the organelles responsible for photosynthesis in green plants. Onion cells do not contain chlorophyll, so they do not require chloroplasts for photosynthetic processes.
Do onions cell have chloroplasts?
No

What type of cell did the onion cell represent?
The onion cell represents a plant cell, specifically from the onion bulb (Allium cepa). Plant cells, like those in onions, have a distinct cell wall, which provides structural support, as well as chloroplasts for photosynthesis (though onion cells typically do not contain chloroplasts as they grow underground). They also feature a large central vacuole that helps maintain turgor pressure. These characteristics differentiate them from animal cells, which lack a cell wall and chloroplasts.
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
