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.
What causes the shape of a human cheek cell to be different from the shape of onion's epidermal cell?
The shape of a human cheek cell is influenced by its function and structure in the body, which includes maintaining tissue structure and facilitating absorption. Onion epidermal cells, on the other hand, are specialized for protection and support, resulting in a different shape and structure to serve their purpose in the plant. This difference in function leads to the variation in cell shape between the two organisms.
Are chloroplasts visible in onion and cheek cells?
No chloroplasts in cheek and onion cells
Why are onion cells in a sheet and cheek cells individual units?
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.
Name the filamentous pigmented and keratinized structure that projects from the epidermal surface?
Hair

What epidermal cell compose about 8 percent epidermal cells?
Merkel cells compose about 8% of the epidermal cells. These specialized cells are found in the deepest part of the epidermis and are involved in the sensation of touch.
Does HIV attack epidermal cells?
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
What cells line the ventricle of the brain?
Ependymal cells
Do cheek cells have vacuoles?
Cheek cells usually have a vacuole. The cheek cells are part of the human cells and are therefore classified as animal cells which usually have vacuoles.
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.
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.
