To determine which of the following options is a function of mitosis, you can analyze each choice individually:
1. To make a cell exit the cell cycle: Mitosis is actually a phase of the cell cycle, specifically the process of cell division that results in two identical daughter cells. Therefore, it does not play a role in making a cell exit the cell cycle.
2. To send chemical signals throughout the body: The process responsible for sending chemical signals throughout the body is called cell signaling, which involves molecules such as hormones, neurotransmitters, and cytokines. Mitosis is not directly involved in this process.
3. To repair damaged tissue: Tissue repair typically occurs through a process called regeneration, which involves cells dividing and differentiating to replace damaged cells. Mitosis plays a significant role in the regeneration of tissues and organs by replicating and producing new cells.
4. To cause a cell to grow: While it is true that cell growth can occur during the cell cycle, specifically during the interphase stage, mitosis itself is not directly responsible for causing a cell to grow. It is primarily involved in the division of replicated genetic material into two daughter cells.
Therefore, the correct answer is: "to repair damaged tissue."
