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.
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.

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.

Epidermal cells are supplied with nutrients from blood vessels in the
If you're talking about kitchen sponges, they do not have cells. However, sea sponges have 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.
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
