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.

WebCryptomonads, cryptoprotists, or cryptophytes, as these algae are commonly called, are unicellular, biflagellate protists. They are variously classified as belonging to the phylum (division) Cryptophyta, class Cryptophyceae, order Cryptomonadales, or phylum Cryptista sensu Cavalier-Smith (1986). WebPlants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.
