Question

The process of differentiation is
• a process by which cells die.
• a process by which cells become specialized.
• a process by which cells divide.
• a process by which cells repair themselves.

Answer 1

The process of differentiation is a process by which cells become specialized.

(It's not cell death—that's apoptosis; not cell division—that's mitosis/meiosis; and while differentiation can help tissue repair, repair itself is not the definition.)
