The two layers containing dead cells in the skin are:
b) stratum corneum and d) stratum lucidum.
The stratum corneum is the outermost layer of the epidermis. It consists of dead keratinized cells that provide a tough barrier against environmental damage, pathogens, and water loss. These cells are continuously shed and replaced from the layers beneath.
The stratum lucidum is found only in thick skin areas (like the palms and soles) and serves as an additional protective layer. It consists of a few rows of translucent, dead keratinocytes that help reduce friction and shear forces that might harm the skin.
The other layers mentioned, such as the stratum basale, are composed of living cells, playing crucial roles in cell division and replenishment of the skin layers.
