No
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.
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.
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.
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.
The structures that are found in the hydrilla which are not found in the onion cell are chloroplasts, specifically the stomata and chlorophyll. Onions lack these structures because they grow underground.
animal cells do not have chloroplasts
The only cell that has chloroplasts is plant cell
Animal cells have a cell membrane but do not have chloroplasts or a cell wall.
Onions are underground structures. They do not get sunlight.
The bulb of the onion does not but the leaves of the onion plant do.
