Hardening of the cells is called sclerosis. This term is commonly used in medical contexts to describe the process of abnormal thickening, hardening, and scarring of tissues.
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.
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.
Stratum granulosum Once again, stratum granulosum is one of epidermal layers: not epidermal cells. My answer to this question is: Flattened cells of stratum granulosum that are going through keratinization process contain kerathyaline and lamellated granules.
In Dugesia, or planarians, nutrients are distributed to epidermal cells primarily through a process called diffusion. The gastrovascular cavity, which is a central digestive space, breaks down food and allows nutrients to diffuse into surrounding tissues, including the epidermis. This diffusion occurs because of the concentration gradient, with nutrients moving from areas of higher concentration in the gastrovascular cavity to lower concentration in the epidermal cells. Additionally, the extensive branching of the gastrovascular system facilitates efficient nutrient distribution throughout the organism.

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.
Langerhans cells
Epidermal cells are supplied with nutrients from blood vessels in the
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.
Keratin is a protein responsible for the hardening process(keratinised) that cells undergo when they change from living cells with a nucleus to dead cells without a nucleus.
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
Ependymal cells
The epidermal cells of an onion are located on the outermost layer of the onion bulb, forming a protective barrier.
