When a diploid cell divides by mitosis, what type of daughter cells are produced?

When a diploid cell undergoes mitosis, it replicates its genetic material and divides to produce daughter cells that are genetically identical to the original cell. A diploid cell contains two sets of chromosomes, one set inherited from each parent, and has a total of two complete sets of chromosomes. Therefore, during mitosis, each daughter cell retains this diploid state, resulting in two diploid daughter cells. This process is crucial for growth, tissue repair, and asexual reproduction in organisms.

The other possibilities, such as haploid, tetraploid, and monoploid, represent different chromosome configurations not produced during the mitotic division of a diploid cell. A haploid cell contains only one set of chromosomes and is typically formed during meiosis, not mitosis. Tetraploid cells contain four sets of chromosomes, which can occur in specific conditions but are not a direct result of mitotic division in diploid cells. A monoploid cell is similar to haploid and also contains one set of chromosomes, which is not what occurs following mitosis in diploid cells. Thus, the production of diploid daughter cells ensures the maintenance of the chromosome number throughout the cell cycle.
