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. WebOct 5, 2024 · Cryptomonads are small (∼5–50 ∝m in length), bean-shaped, motile cells ( Figure 1 ). Some are capable of forming cysts or palmellae (clusters of cells held together …
Webal. (2002), Cryptomonas spp. and Plagioselmis spp. are respectively distributed in the Y and X2 coda. In particular, the Y functional group shows Cryptomo-nas spp. as typical representatives, well-adapted to live in a wide range of habitats, mostly in small, enriched lakes; nevertheless, their dynamics are vul-nerable to the feeding activity of ... WebAll functional groups included one or more species (X2-Rhodomonas spp.; Y-Cryptomonas spp.; F-Oocystis lacustris; K-Aphanocapsa spp.) selected by resources, especially phosphorus. Species of Cryptomonas (group Y) dominated during the mixing period (winter season) in conditions of low light and relatively high availability of dissolved nutrients.
