Question 13

Why is it difficult to explain one certain way a protist reproduces? Please use complete sentences and proper grammar.

Answer 13

There are two main types of reproduction for protists: Asexual reproduction and sexual reproduction. Protists are confusing because some protists only use asexual reproduction. Some use asexual reproduction at one stage, then use sexual reproduction at another stage. Some protists even alternate between sexual and asexual reproduction based on generations. Some reproduce asexually until they become stressed, reproduce sexually, then reproduce asexually when conditions improve. Because of this, it is difficult to explain one main way that protists reproduce.
