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 cheek cells do not contain pigments. Pigments such as melanin are produced by melanocytes located in the basal layer of the epidermis and transferred to surrounding keratinocytes, providing skin coloration. Cheek cells mainly consist of epithelial cells that do not contain melanin.
Stratum granulosum
Guard cells contain specialized organelles called chloroplasts, which are responsible for photosynthesis. These chloroplasts enable guard cells to produce sugars and other molecules needed for energy. The surrounding epidermal cells, on the other hand, do not typically contain chloroplasts as they are not directly involved in photosynthesis.
Guard cells, but mesophylls also have them

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.

Hair follicles are tube-like structures that extend from the epidermis into the dermis. They are comprised of epidermal cells and contain the hair shaft.
Guard cells, but mesophylls also have them
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.
Langerhans 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.
Mesophyllic cells are the cells that lie between the lower and upper epidermal layers of leaves and contain chloroplasts necessary for the production of sugars from sunlight.
