What type of reproduction do most protozoa undergo?

Most protozoa primarily reproduce through asexual methods, with binary fission being the most common form. During binary fission, a single protozoan cell divides into two identical daughter cells, allowing for rapid population growth. While some protozoa can also undergo sexual reproduction, particularly under certain environmental stresses or for genetic variation, it is not the predominant form of reproduction for the majority of protozoan species.

In the context of this question, asexual reproduction, including binary fission, is the more relevant answer reflecting the reproductive strategies used by most protozoa. Sexual reproduction, while it does occur in some cases, is less common among the diverse range of protozoan organisms. Therefore, understanding the typical reproductive mechanisms of protozoa highlights the significance of asexual reproduction (especially binary fission) in their life cycles.
