To determine which of the following is a function of mitosis, we need to understand what mitosis is and how it functions. Mitosis is a process of cell division that occurs in eukaryotic cells, where a single cell divides into two identical daughter cells. It is important for growth, development, and repair within organisms.
Now let's evaluate each option to see if it aligns with the function of mitosis:
A) To send chemical signals throughout the body: This is not a function of mitosis. Chemical signaling throughout the body relies on processes such as secretion and response to specific signals by target cells, not cell division.
B) To repair damaged tissue: This is a valid function of mitosis. When tissues get damaged, mitosis helps replace the damaged cells by dividing and producing new identical cells to facilitate tissue repair.
C) To make a cell exit the cell cycle: This is not a function of mitosis. The cell cycle is a series of events that cells undergo to divide and replicate their DNA, and mitosis is a part of the cell cycle.
D) To cause a cell to grow: While mitosis is involved in cell growth, it is not the only factor responsible for causing a cell to grow. Other processes like cell metabolism, protein synthesis, and cell signaling are also involved in cell growth.
Therefore, the correct answer is B) to repair damaged tissue.
