because it is only found in green parts of plants
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.
Potato cells have larger, more angular shape and contain starch granules, while onion cells are smaller and have a more rectangular shape with a distinct cell wall. Additionally, potato cells lack the characteristic onion cell layers seen in onion cells.
the reason you wouldn't see chloroplasts is because the onion root tip is underground where light can not reach and why would it need chloroplasts if it didn't need to produce energy form light?
Because onion bulb develops underground and it is meant for food storage to overcome adverse environmental conditions. The skin of the bulb need not loose water and take part in gaseous exchange. Therefore, it does not have guard cells and stomata.
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.
the chloroplast
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.
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.
The main function of the onion skin cell is to protect the rest of the onion
Onion leaves have chloroplast but not the vegetable(bulb)....
Of course not they do not.They do not have DNA for that.
Potato cells have larger, more angular shape and contain starch granules, while onion cells are smaller and have a more rectangular shape with a distinct cell wall. Additionally, potato cells lack the characteristic onion cell layers seen in onion cells.
No. Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form.
A cell wall.
The structure of an onion skin cell differs from other plant cells in that it lacks chloroplasts, which are responsible for photosynthesis. Onion skin cells also have a unique rectangular shape and a thin cell wall compared to other plant cells.
Onion cells are plant cells, so they have a cell wall and more angular shape (but no chloroplasts, like some plant cells, since they are not part of the photosynthesizing part of the onion plant) Human cheek cells are animal cells, so the biggest difference is that they have no cell wall and thus a rounder shape.
