What type of cell division is essential for growth and repair of body tissues?

• A. Meiosis
• B. Mitosis
• C. Asexual Reproduction
• D. Binary Fission

Answer: (B)

Mitosis is the type of cell division essential for the growth and repair of body tissues. During mitosis, a single cell divides to produce two genetically identical daughter cells, each containing the same number of chromosomes as the original cell. This process allows for an increase in cell number without changing the genetic material, which is crucial for growth, development, and healing in multicellular organisms. In tissues where cell turnover is high, such as in skin or blood, mitosis is constantly occurring to replace lost or damaged cells. For instance, when you have a cut and the skin needs to heal, mitosis enables the rapid production of new skin cells to close the wound. In contrast, meiosis is a specialized form of division that produces gametes (sperm and eggs) and is not involved in general tissue growth or repair. Asexual reproduction refers to processes that generate new individual organisms and is not directly linked to the repair of tissues in a multicellular body. Binary fission is a method of asexual reproduction found in prokaryotic organisms, such as bacteria, and does not apply to the cell division needed for growth and repair in complex organisms.
