Cell division is the process by which a single cell duplicates its DNA and cellular structures, ultimately splitting into two daughter cells capable of repeating this process. This leads to exponential growth, as one cell becomes two, then four, and so on. The discussion highlights that understanding cell division can vary based on the type of cell in question, such as bacterial, yeast, or mammalian cells. Additionally, it emphasizes that much of cellular activity revolves around preparing for or recovering from division, underscoring the fundamental role of reproduction in life.
