In onion epidermal cells, the cell wall is relatively thick, providing structural support. However, the nuclei of these cells may not always be easily visible under a light microscope due to their small size and the staining techniques used. While the cell wall is prominent, the visibility of the nucleus can vary depending on the preparation and staining of the sample.
What else can I help you with?
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
How do you account for the fact that some of the nuclei appear to be centrally located in the cells of onion epidermal cells?
Becuase the necleus is in the middleYes, plants are made of cells that contain nuclei. The only living things that do not contain nuclei in their cells are bacteria.Plant cells have nuclei
Where can you find onion epidermal cells?
Onion epidermal cells can be found on the outer layer of an onion bulb, specifically in the thin, transparent skin that covers the onion. This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
What is the size of an epidermal onion cell?
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
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)
Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
Where are the epidermal cells of an onion located?
The epidermal cells of an onion are located on the outermost layer of the onion bulb, forming a protective barrier.
How do you account for the fact that some of the nuclei appear to be centrally located in the cells of onion epidermal cells?
Becuase the necleus is in the middleYes, plants are made of cells that contain nuclei. The only living things that do not contain nuclei in their cells are bacteria.Plant cells have nuclei
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.
Are the cell wall thick and are the nucleic invisible in the onion epidermal cell?
In onion epidermal cells, the cell wall is relatively thick compared to the cell membrane, providing structural support. However, the nucleic structures, such as the nucleus, may not be easily visible under a light microscope due to the thinness of the cytoplasm and the transparency of the onion cells. Staining techniques can help visualize the nucleus more clearly.
What is the cell of onion peel?
The cell of an onion peel is a plant cell. The cells of the onion peel do not have chloroplasts because the onion bulb (white part) grows under ground and its cells do not carry out photosynthesis.
Where can you find onion epidermal cells and what is their significance in plant biology?
Onion epidermal cells can be found in the thin, transparent layer on the surface of an onion bulb. These cells are significant in plant biology because they are commonly used in science experiments to study cell structure, division, and function. They are also used to observe processes such as osmosis and plasmolysis.
Where can you find onion epidermal cells?

This layer serves as a protective barrier for the bulb and is often used in biology labs for microscopic studies due to its easy accessibility and clear cell structure. To observe these cells, you can peel off a small section of the onion's skin and place it on a microscope slide.
What structure observe in onion epidermal cells are not present in human epithelial cells?
The structure of onion epidermal cells refers to the arrangement of tissues in this cells. You can find the structure of onion epidermal cells online athttp://biology.touchspin.com/onion_epidermis.php. The structures observed in an onion epidermal cell, which are not present in the human epithelial cells are cell wall, central vacuole and vacuolar membrane.
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.
Is the chloroplast in onion cells larger than the nuclei?
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.
Does an onion epidermal cell have depth?
yes
