What is an example of Sporozoans?
Sporozoans are organisms that are characterized by being one-celled, non-motile, parasitic, and spore-forming. Most of them have an alternation of sexual and asexual stages in their life cycle. An example of sporozoan is the Plasmodium falciparum, which is the causative agent of malaria.
What type of parasites are Apicomplexa?
The Apicomplexa are a phylum of diverse obligate intracellular parasites including Plasmodium spp., the cause of malaria; Toxoplasma gondii and Cryptosporidium parvum, opportunistic pathogens of immunocompromised individuals; and Eimeria spp. and Theileria spp., parasites of considerable agricultural importance.
Which of the following is an example of an Apicomplexan?
In humans, the medically-important apicomplexans include Babesia sp. (causing babesiosis), Plasmodium spp. (causing malaria), Cryptosporidium parvum (causing cryptosporidiosis), Cyclospora cayetanensis (causing cyclosporiasis), Isospora belli (causing isosporiasis), Toxoplasma gondii (causing toxoplasmosis), etc.

How are Apicomplexans classified?
The Apicomplexa (also called Apicomplexia) are a large phylum of parasitic alveolates. Most of them possess a unique form of organelle that comprises a type of non-photosynthetic plastid called an apicoplast, and an apical complex structure.
