Compare and contrast protozoan cysts fungal spores and bacterial endospores

Bacterial spores or endospores are not for reproduction. They do not improve the total number of bacterial cells. Whereas for fungal spores, they are formed from aerial hyphae. They can either be asexual spores which when germinated will be a new but genetically identical to the parent. Sexual spores result from the combination or mixture of nuclei from two opposite mating strains of the same species.
