Cryptomonas cells are fairly large; they average about 40 micrometers in size and often take the shape of an oval or ovoid. [4] . There are two flagella present, yet the two flagella are not equally sized. [1] . One is shorter and curled and the other one is longer and straight. [1] .

Cryptomonas ovata (Figs. 3B, 4D, E, 15C, D) Cells are ellipsoid to oval, and they may be slightly curved. Cells measure 20–80 μm in length, 6–20 μm in width, and 5–18 μm in depth and appear somewhat flattened.

2020年10月5日 · Cryptomonads (or cryptophytes) are single-celled protists found in marine, brackish and freshwater habitats the world over. Although not particularly abundant, cryptomonads are an important part of the aquatic food chain.

2010年8月25日 · Cryptomonas is a genus of phytoplankton that inhabit freshwater aquatic systems. The genus belongs to a larger collective of organisms called "cryptomonads", which consists of of biflagellate organisms. Cells tend to be rather large, varying in shape between ovoid and elliptical, averaging 40 um in size.

Low levels of bacterial ingestion by two cultures of Cryptomonas (C. ovata and C. erosa) and a population collected from a humic mesotrophic lake, using fluorescent polystyrene microspheres. However <2% of carbon content per day was accumulated through bactivory (Tranvik, Porter and Sieburth 1989).

Cryptomonas ovata is a species of Cryptophyceae in the family Cryptomonadaceae. They are associated with freshwater habitat. They are native to Pernambuco, Paraná, Rio De Janeiro, Rio Grande Do Sul, Minas Gerais, and SãO Paulo.

Cryptomonas ovata is a species in Chromista (brown algae and allies) with 3 observations

2015年1月1日 · A second type of rhizostyle, reported for Cryptomonas ovata (Roberts, 1984, Hill, 1990) and Cryptomonas theta (= Guillardia theta) (Gillott and Gibbs, 1983), lacks wings/keels coming off the microtubules. This type of rhizostyle usually terminates anterior to the nucleus (Roberts, 1984).

A state-transition-’like’ behavior in cryptophytes has been observed in Cryptomonas ovata; energy delivering to the photosystems was controlled by small conformational changes/uncoupling of the pigment-proteins and considered to be the major photoprotective mechanism in cryptophytes (Snyder and Biggins, 1987).
