The cryptomonads (or cryptophytes) are a group of algae, most of which have plastids. They are common in freshwater, and also occur in marine and brackish habitats. Each cell is around 10–50 μm in size and flattened in shape, with an anterior groove or pocket. At the edge of the pocket there are typically two slightly unequal flagella. Traditionally, Cryptomonas was considered to be 3 separate genera: Chilomonas, Cryptomonas and Campylomonas. Before further molecular analysis, Cryptomonas have been characterized by mainly morphological characters, such as cell size, cell shape, number and color of plastids. See more Cryptomonas is the name-giving genus of the Cryptomonads established by German biologist Christian Gottfried Ehrenberg in 1831. The algae are common in freshwater habitats and brackish water worldwide and often … See more Cryptomonas are also photolithotrophs that contribute to oxygenic carbon fixation making them greatly critical to the carbon levels of fresh water environments. See more Organisms are asymmetric with a transparent membrane on the outside. The membrane is not ciliated. Cryptomonas cells are fairly large; they average about 40 micrometers in size … See more Cryptomonas has the meaning of hidden small flagellates from “crypto” and “monas”. See more Species within Cryptomonas contain four genomes: the nuclear, the nucleomorph, the plastid, and mitochondrial genomes. The plastid genome contains 118 kilobase pairs and … See more Replication of Cryptomonas occurs in early summer when fresh water species are also reproducing. Cryptomonas replicates via mitosis that only takes about ten minutes. Sexual … See more Cryptomonas are large in size, grow rather slowly, and are limited in nutrients. It also migrates between depths of water in order to reach depths that are ideal for photosynthesis and … See more
