Cryptophyta

Characters specific to the Cryptophytes

Of the trichocystes or éjectosomes is structures specific to this group being used to neutralize preys.
the ventral face of the cell is traversed by a furrow finished by a major depression . This one is papered trichocystes described above.
Presence of two " Body of Maupas" , close to the depression, which is structures whose function remains unknown.
Two Whips S whose longest carries two lines of Mastigonèmes .
the Mitose presents characteristics suitable for the group. It is known as open and does not utilize of Centriole S.
the Chloroplaste is equipped with four membrane S, as at the Chlorarachniophyte S and in the brown Lignée. This is the sign of a Endosymbiose of a photosynthetic Eucaryote. Traces of this endosymbiote are still visible at some Cryptophytes , in particular the presence of a nucléomorphe , which is the vestige of the core of the captured eucaryote. The study of ARN R 18S of this nucléomorphe indicates that the endosymbiote is close to the Rhodophyta.
In the chloroplast, the Thylakoïde S are grouped per pairs.

Ecology

The Cryptophytes meet in all the types of aquatic environments: oceanic mediums with fresh water while passing by pore waters of the wet terrestrial environments.

Certain species became parasitic S Intestin with Métazoaire S. Some are Endosymbiote S of Dinophyte S. Some live in a symbiotic way in the ectoplasm of the Radiolaire S.
