What is an epidermal cell?
An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
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.
Which cell junctions prevent epidermal cells from separating under tension?
Desmosomes are the cell junctions that prevent epidermal cells from separating under tension. They form strong connections between neighboring cells by anchoring to the cell's cytoskeleton, providing structural stability to tissues exposed to mechanical stress.
What is the substance that helps promote mitosis in epidermal skin?
Epidermal growth factor (EGF) is the substance that helps promote mitosis in epidermal skin cells. EGF stimulates cell growth and division in the epidermis, aiding in the regeneration and repair of skin tissue.
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.

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 Squamous cell carcinoma involve dermal cells?
No, they involve superficial epidermal cells
Do epidermis cells have a secondary cell wall?
No, epidermal cells do not have a secondary cell wall. The primary cell wall of epidermal cells is composed mainly of cellulose, hemicellulose, and pectin, providing support and protection to the cell. Secondary cell walls are found in specific types of cells, such as xylem cells in plants, for additional structural support.
Which skin cancer arises from the youngest epidermal cells?
basal cell carcinoma
Which is an epidermal cell with an immunological function?
Langerhans cells are epidermal cells that play a key role in the immune response by capturing and presenting antigens to immune cells. They are part of the skin's immune system and help in defending against pathogens.

How can epidermal cell show that plant grows in a dry habitat?
Alternatively, in plants growing in dry habitats, the epidermal cell walls and cuticles are typically very thick. In pines (Pinus sp.) the epidermal cells of the needles have layers of secondary wall material that almost fill the cell cavity.

What cell structure is in the guard cells but not in other epidermal cells?
Guard cells contain chloroplasts, which are responsible for photosynthesis, while other epidermal cells do not typically contain chloroplasts. Chloroplasts are important for the production of sugars and energy through the process of photosynthesis in guard cells.
