What is the main function of squamous cells in the skin?

  1. To store fat

  2. Protect layers below the stratum corneum

  3. Produce melanin

  4. Chemical conversion

The correct answer is: Protect layers below the stratum corneum

Squamous cells are a type of skin cell that make up the outermost layer of skin, known as the epidermis. They are responsible for protecting the underlying layers of the skin, as they form a barrier against environmental toxins, UV radiation, and bacteria. They do not store fat or produce melanin, and they do not play a role in chemical conversion. Therefore, options A, C, and D can be ruled out as incorrect.
