They are usually horn shaped, and reaching lengths of 2 millimeters, they are among the biggest known unicellular organisms. Appearance and characteristics The body, or Cortex anatomy cortex , is generally horn shaped, hence the association with the Stentor Greek herald and the former name trumpet animalcule , with a ring of prominent cilia around the anterior bell that sweep in food and aid in swimming. Some reach several millimeters in length, making them among the largest microorganism single celled organisms . Stentor can come in different colors. As in many freshwater protozoans, the Stentor has a contractile vacuole . Because the concentration of salt inside the cell and in the surrounding freshwater is different, Stentor must store water that enters it by osmosis and then discharge it from the vacuole. They can Regeneration biology regenerate , and small fragments can grow into full organisms. Each cell has one often elongated macronucleus and several micronucleus micronuclei .

Eur J Protistol 37 4 , 379 390 ref There is only one known species in this genus. This species was isolated in 2002 from a free living Cryptomonad cryptophyte Chilomonas paramaecium . The type species is Cryptophagus subtilis . Life cycle The life cycle begins with the adhesion of the anterior tip of the parasite, followed by the penetration of the flagellated sporozoite , into a specialized region at the base of a Chilomonas flagella . The trophozoite grows within the host cytoplasm. After 4 5 successive nuclear mitosis mitoses the sporozoites bud on the surface where they acquire flagellae, microneme s and other apical structures. Mitosis is closed with an external spindle lacking a paradesmosis . A sporangium is not formed but a cyst may occur within the host. Description The sporozoite has an elongated shape with an apical complex, a central Cell nucleus nucleus and two flagellae which are inserted at the base of the pseudoconoid . Two microtubular roots lie deep to the plasma membrane and are attached to each basal body . The apical complex consistes of a set of 10 14 microneme s and a train of dumb bell like vesicles which converge toward the tip of the pseudoconoid. The micronemes are outlined by a four microtubule fibre. The dumb bell like vesicles are associated with a three microtubules in a rake like fibre. The mitochondria l network has few cristae and a fairly reduced dense matrix. One large vacuole containing microfilamentous material is present and is connected to the n ... more details

Orphan date April 2012 Lipophosphoglycan sometimes abbreviated to LPG is a class of molecule found on the surface of some eukaryotes , in particular protozoa . A lipophosphoglycan is made up of two parts a lipid part and a polysaccharide also called glycan part. The two are linked by a phosphodiester bond, hence the name lipo phospho glycan. The lipid part of the lipophosphoglycan is normally found embedded in the cell membrane and the glycan part forms part of the coat of macromolecules on the cell surface. A notable group of organisms which have an extensive lipophosphoglycan coat are the Leishmania species , a group of single cell biology cell ed protozoa n parasite which cause Leishmaniasis in many mammals , including humans .
