What is the primary purpose of cell division in organisms?

The primary purpose of cell division in organisms is to replicate contents and form new cells. This process is essential for growth, development, and repair in multicellular organisms. During cell division, specifically through processes such as mitosis and cytokinesis, a parent cell divides to produce two daughter cells that are genetically identical to the original cell. This not only allows for the replacement of old or damaged cells but also supports the increase in organism size and the development of tissues.

While replicating genetic material is a critical step in cell division, it is part of a larger process that facilitates the actual formation of new cells. Cell differentiation and metabolic rates are important in different contexts, but they do not encompass the overarching goal of cell division itself, which is the production of new cells to maintain and propagate life. Therefore, the correct answer to the question reflects the comprehensive role of cell division in producing new cells, making it essential for the continuation of life and the functioning of an organism.
