What process is responsible for the generation of new cells?

• A. Mitosis
• B. Meiosis
• C. Photosynthesis
• D. DNA replication

Answer: (A)

Mitosis is the process responsible for the generation of new cells in multicellular organisms. It involves a series of steps through which a single cell divides to produce two identical daughter cells, each containing the same genetic material as the original cell. This process is essential for growth, development, and repair of tissues in the body. Mitosis ensures that when cells divide, they maintain the same number of chromosomes, allowing for proper cellular function and genetic continuity. Other processes listed do not directly pertain to the generation of new cells in this context. Meiosis, for instance, is a specialized form of cell division that occurs in the production of gametes (sperm and egg cells) and reduces the chromosome number by half for sexual reproduction. Photosynthesis is a process used by plants to convert light energy into chemical energy, producing glucose and oxygen, and is not directly involved in cell division. DNA replication is the process of copying the genetic material in a cell before it divides, but it is a step within mitosis rather than a separate process that generates new cells.
