Rhizopus Rhizopus Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found on a wide variety of organic substrates, including "mature fruits and vegetables", jellies, syrups, leather, bread, peanuts, and tobacco. They are multicellular. Some "Rhizopus" species are opportunistic agents of human zygomycosis (fungal infection) and can be fatal. "Rhizopus" infections may also be a complication of diabetic ketoacidosis. This widespread genus includes at least eight species. "Rhizopus" species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They reproduce by forming asexual and sexual spores. In asexual reproduction,
Chromera velia for understanding the biochemistry, physiology and evolution of the malaria parasite, other apicomplexan parasites, and dinoflagellates. "Apicoplast" is a specialised word, derived from the word "plastid". Initially the word plastid was more suitable than "chloroplast" when describing organelles of apparent algal descent in any protist, but that lack any chlorophyll or light absorbing pigment. Those found in apicomplexan parasites are a prominent example. The majority of members of the apicomplexan lineage still contain a genome in the plastid, indicating the organelle of the lineage's ancestors was once photosynthetic, but these plastids have no light absorbing pigments or light reaction machinery.
