It is possible to identify heterotrophic protists under a microscope by looking for indicators of locomotion. All heterotrophic protists must consume other organisms for food and therefore must be capable of movement, unlike autotrophic protists that produce their own energy and do not need to move.

Parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
