Are the nuclei invisible in the onion epidermal cells?
It can seen vaguely and invisible under the microscope
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.
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
Why onion epidermal cell does not contain chloroplast?
Onion epidermal cells lack chloroplasts because they are specialized for protection and water retention rather than photosynthesis. Chloroplasts are primarily found in cells that are involved in photosynthesis, such as cells in the mesophyll layer of plant leaves. Onion epidermal cells serve a different function in the plant's structure and are therefore not needed to contain chloroplasts.
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 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.

Does an onion epidermal cell have depth?
yes
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.
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
What is a epidermal cell?
it is a thin layer that can be peeled out from an onion.
Why onion epidermal cell does not contain chloroplast?
Onion epidermal cells lack chloroplasts because they are specialized for protection and water retention rather than photosynthesis. Chloroplasts are primarily found in cells that are involved in photosynthesis, such as cells in the mesophyll layer of plant leaves. Onion epidermal cells serve a different function in the plant's structure and are therefore not needed to contain chloroplasts.
Is mitochondria more abundant in human epithelial cells or in onion epidermal cells?
Mitochondria are typically more abundant in human epithelial cells compared to onion epidermal cells. Human epithelial cells have high energy demands due to their involvement in absorption, secretion, and barrier functions, necessitating more mitochondria for ATP production. Onion epidermal cells primarily serve a protective function, so they generally have fewer mitochondria.
Which structure in an onion epidermal cell is semipermeable?
The cell membrane is the semipermeable structure in an onion epidermal cell. It regulates the passage of molecules in and out of the cell, allowing only certain substances to pass through while restricting others.
What is the function of epidermal cells in sponges?
Epidermal cells in sponges serve as a protective barrier, helping to prevent pathogens and debris from entering the sponge's body. They also play a role in gas exchange and waste removal by allowing for the diffusion of molecules across their cell membranes. Additionally, epidermal cells can secrete substances that aid in capturing food particles from the water.
