No chloroplasts in cheek and onion cells
Cheek cells are flat, irregularly shaped, and have a nucleus. Leaf cells contain chloroplasts for photosynthesis and have a defined cell wall. Onion cells have a distinct rectangular shape, lack chloroplasts, and contain a large central vacuole.
The difference between potato cells and onion cells, check cells, and lettuce cells is the presence of starch in the potato cells chloroplast organelles. The difference between cheek cells and the rest is easier the cheek cells do not have chloroplasts at all.
Due to the techniques of obtaining the samples, onion cells remain intact in the tissue, but because cheek cells are obtained by rubbing a toothpick on your cheek, you are disrupting the cheek tissue, and instead of getting a sheet of cheek cells, you get individual cheek cells.
Onion peel cells are plant cells that have a rigid cell wall made of cellulose and may contain chloroplasts for photosynthesis. Human cheek cells are animal cells that lack a cell wall, have a flexible cell membrane, and contain a nucleus. Additionally, human cheek cells are eukaryotic, while onion peel cells are prokaryotic.
There are no chloroplasts in bulb.Thats because they do not get sunlight.

Between the 2 cells that are cheek and onion cells, the one that has a regular arrangement and structure are onion cells. Cheek cells have an irregular shape.
Cheek cells are typically larger than onion cells. Cheek cells are human epithelial cells that make up the inside lining of the mouth, while onion cells are plant cells found in the epidermis of onion bulbs. Cheek cells are usually around 30-40 micrometers in size, while onion cells are generally smaller at around 0.1-0.2 millimeters.

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.
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.
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.
The bulb of the onion does not but the leaves of the onion plant do.
Cheek cells are only found in animals, whereas onion cells are found in platns, particularly onion cells. Cheek cells, being animal cells, do not contain a cell wall as onion cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do. Being grown underground, it receives nutrients directly from the soil, so chloraplasts are not evident. This is also why onions are never green, since chloroplasts contain chlorpohyll, a pigment which gives plants its green color. Basically, cheek cells are found in animals, and onion cells are found in plants.
