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.
Granular cells, also known as keratinocytes, contain keratohyaline granules in the epidermis. These granules help with the process of keratinization. Lamellar granules, on the other hand, are found in the stratum granulosum layer of the epidermis and are responsible for helping to form the skin barrier by releasing lipids.

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
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.
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.
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
Ependymal cells
Epidermal cells undergo a process called keratinization to produce nails. During keratinization, the epidermal cells in the nail matrix produce keratin, a tough protein that forms the structure of the nail plate. As these cells mature and move upwards, they become tightly packed and eventually form the hardened nail plate that we see.
Granular cells, also known as keratinocytes, contain keratohyaline granules in the epidermis. These granules help with the process of keratinization. Lamellar granules, on the other hand, are found in the stratum granulosum layer of the epidermis and are responsible for helping to form the skin barrier by releasing lipids.
