An apicoplast is a derived non-photosynthetic plastid found in most Apicomplexa, including Toxoplasma gondii, and Plasmodium falciparum and other Plasmodium spp. (parasites causing malaria), but not in others such as Cryptosporidium. It originated from algae through secondary endosymbiosis; there is debate as to whether this was a green or red alga. The apicoplast is surrounded by four membranes within the outermost part of the endomembrane system. The apicoplast hosts important metabolic pathways like fatty acid synthesis, isoprenoid precursor synthesis and parts of the heme biosynthetic path

==Significance== Apicoplasts are a relict, nonphotosynthetic plastid found in most protozoan parasites belonging to the phylum Apicomplexa. Among the most infamous apicomplexan parasites is Plasmodium falciparum, a causative agent of severe malaria. Because apicoplasts are vital to parasite survival, they provide an enticing target for antimalarial drugs. Specifically, apicoplasts' plant-like properties provide a target for herbicidal drugs. And, with the emergence of malarial strains resistant to current treatments it is paramount that novel therapies, like herbicides, are explored and understood. Furthermore, herbicides may be able to specifically target the parasite's plant-like apicoplast without any noticeable effect on the mammalian host's cells.
