What type of reproduction in unicellular organisms is achieved through cell division?

The type of reproduction in unicellular organisms that is achieved through cell division is asexual reproduction. This process allows organisms to reproduce without the genetic contribution from a second parent, resulting in offspring that are genetically identical to the parent cell.

In unicellular organisms such as bacteria and some protists, asexual reproduction occurs primarily through cell division methods like binary fission, where a single cell divides into two identical daughter cells. This is a specific mechanism of asexual reproduction that enhances the ability of these organisms to rapidly increase their population under favorable conditions.

The concept of asexual reproduction encompasses various processes, including binary fission, but it specifically refers to the overall ability of an organism to propagate without sexual reproduction. Therefore, identifying asexual reproduction as the general form of reproduction in unicellular organisms is accurate.
