Which process is responsible for cellular reproduction in prokaryotic organisms?

• A. Binary fission
• B. Mitosis
• C. Regeneration
• D. Meiosis

Answer: (A)

The process responsible for cellular reproduction in prokaryotic organisms is binary fission. This is a form of asexual reproduction where a single prokaryotic cell divides into two genetically identical daughter cells. During binary fission, the circular DNA molecule of the prokaryote replicates and attaches to different parts of the cell membrane. As the cell grows in size, it begins to elongate, and eventually, the membrane invaginates, leading to the separation of the two daughter cells. This method of reproduction is efficient and allows for rapid population growth, making it well-suited for prokaryotic organisms that need to populate environments quickly. In contrast, mitosis is a process that eukaryotic cells use for division and is more complex, involving multiple stages and the organization of chromosomes. Regeneration refers to the process by which organisms can regrow certain parts, and meiosis is involved in sexual reproduction leading to the formation of gametes, which does not occur in prokaryotic organisms. Thus, binary fission is uniquely suited to the reproductive needs of prokaryotic cells.
