No, the nuclei in onion cells are generally larger than the chloroplasts. Nuclei are the control center of the cell and contain genetic material, while chloroplasts are responsible for photosynthesis.

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.
What is bigger cheek cells or onion cells?
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.
Why do onion cells look so different than human cheek cells?
Onion cells are plant cells, characterized by a rigid cell wall and a large central vacuole. Human cheek cells are animal cells, lacking a cell wall and having a prominent nucleus. The differences in structure are due to the different functions and environments of plant and animal cells.
Onion cells and elodea cells structure differences?
Onion cells have a larger rectangular shape with a distinct rectangular cell wall and a central nucleus. Elodea cells are smaller and have a more elongated shape with chloroplasts that move around the cell due to the presence of cytoplasmic streaming. Both types of cells have a cell wall, cell membrane, and cytoplasm, but the arrangement and size of organelles differ.
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.
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.
How do potato cells differ from onion cells?
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.
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.
Did onion has chloroplast?
Onion leaves have chloroplast but not the vegetable(bulb)....
Do onion cells have chloroplast after being taken away from the ground?
Of course not they do not.They do not have DNA for that.
Why do onion skin cells have no chloroplast?
because it is only found in green parts of plants
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.
How do you account for the fact that some of the nuclei appear to be centrally located in the cells of onion epidermal cells?
The observation that some nuclei in onion epidermal cells appear centrally located is likely due to the large size of the nuclei relative to the cell size, as well as the arrangement of other cellular organelles around the nucleus within the cell. The central positioning of nuclei can also be influenced by the need to optimize processes such as gene expression, cell division, and overall cellular function within the confines of the cell.
What is bigger cheek cells or onion cells?
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.
Why would you not find a chloroplast in a onion root cell?
Onion root cells are typically from the underground parts of the plant, where they do not engage in photosynthesis. Chloroplasts, which are responsible for photosynthesis, are found in cells that are exposed to light, such as leaf cells. Therefore, you would not typically find chloroplasts in onion root cells.
What are the differences in cell organelles between onion cells potato cells cheek cells and lettuce cells?
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.
Is chloroplast found in onion?
yes
