Question

Complete the sentences describing the cells and layers of the epidermis. The epidermis consists of multiple layers of epidermal cells called stratum granulosum. These cells produce a tough, fibrous, waterproof protein called keratinocytes which, over time, hardens in a process called keratinization. The cells of the epidermis are produced by the process of _____ in the deepest layer of the epidermis. This layer is called the stratum basale. As new cells are formed, they push older cells further away from the dermis and the blood supply available there. Consequently, the cells die. The dead, hardened outermost cells of the epidermis form the layer called the stratum corneum. These cells eventually are sloughed off. stratum granulosum melanin keratin mitosis dermis keratinization keratinocytes stratum basale stratum corneum melanocytes

Explanation / Answer

Melanin-- The pigment that gives color to the skin is known as melanin and it is produced by the cells which are known as melanocytes.

Keratin--- The protein which plays a major role in making the outer layer of the skin is known as keratin.Keratin that protects epithelial cells from damage or it protects from severe stress.

Melanocytes--- The cells which produce melanin are known as melanocytes.

Mitosis--- The replacement of outer dead cells which contains keratin which makes the epidermis cells to undergo mitosis constantly in skin cells.
