Which process is essential for the growth and repair of tissues?

• A. Meiosis
• B. Photosynthesis
• C. Mitosis
• D. Apoptosis

Answer: (C)

The process that is essential for the growth and repair of tissues is mitosis. Mitosis is a type of cell division that results in two genetically identical daughter cells from a single parent cell. This process is critical during growth phases in multicellular organisms, allowing for the increase in cell number, which contributes to tissue growth. It also plays a vital role in the repair of damaged tissues by generating new cells to replace those that have been lost or injured.

In the context of tissue repair, mitosis ensures that cells can proliferate and help heal wounds or regenerate damaged areas. This ability to create new cells is central to maintaining healthy tissues and organs throughout the lifecycle of an organism.
