The total number of cells in an organism increases as a result of which process?

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

Answer: (A)

Verified step by step guidance

1. Understand the context: The problem is asking about a process that increases the total number of cells in an organism.
2. Identify the processes listed: Mitosis, Apoptosis, Meiosis, and Photosynthesis.
3. Define each process: Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
4. Consider the role of each process: Mitosis is directly involved in increasing the number of cells, as it is responsible for cell division and growth.
5. Conclude which process increases cell number: Since mitosis results in the production of more cells, it is the process that increases the total number of cells in an organism.
