Question
What happens to keratinocytes as they move toward the skin's surface?
Correct Answer
Option B is the correct answer.

As keratinocytes move toward the skin's surface, they die and become flattened, forming the stratum corneum. They lose their nucleus and organelles, becoming tough, protective corneocytes.
Hint
These cells undergo programmed death as they move outward.
