How does mitosis function in the body?

It helps repair tissue damage
It allows cells to divide and multiply
It synthesizes proteins
It transports oxygen in blood

The correct answer is: It allows cells to divide and multiply

Mitosis is a fundamental process that allows cells to divide and multiply, which is crucial for growth, development, and maintaining the integrity of tissues in the body. During mitosis, a single cell goes through a series of well-coordinated phases — prophase, metaphase, anaphase, and telophase — leading to the creation of two genetically identical daughter cells from the original cell. This process is essential not only for normal development but also for replacing damaged or dead cells, thus ensuring that the body can maintain its functions and respond to injuries. The other options, while important aspects of cellular and bodily functions, do not accurately describe the role of mitosis. Repairing tissue damage involves not just cell division, but also other processes such as inflammation and the action of various cell types. Protein synthesis primarily occurs in ribosomes and involves transcription and translation processes, which are separate from cell division. Transportation of oxygen in the blood is a function of red blood cells, distinct from the process of cell division in mitosis. Therefore, the defining characteristic of mitosis is its role in allowing cells to divide and multiply.
