6. What are the different ways that protozoans reproduce?
Protozoans reproduce through several methods including asexual reproduction, sexual reproduction, multiple fission and conjugation.
Asexual reproduction: Protozoa are primarily asexual, but they may also reproduce sexually. This type of reproduction leads to the formation of genetically identical daughter cells, which are clones of the parent.
Sexual reproduction: The sexual reproduction of protozoans involves the fusion of gametes that come from two different individuals. This type of reproduction results in the formation of new genetic combinations.
Multiple fission: This is a type of asexual reproduction in which the protozoan cell divides into several daughter cells. The process occurs in a sequence, and these daughter cells continue to divide and grow until they reach maturity.
Conjugation: Some protozoans can undergo a process called conjugation, in which two individuals of the same species come together and exchange genetic material. This process differs from sexual reproduction in that new offspring are not produced. Instead, conjugation results in the exchange of genetic information that can aid in the organism's survival and adaptation.
