http://culter.colorado.edu/taxa/phylum.php-q-phylum_ID=4.html Cryptophytes are distinguished by the presence of characteristic extrusomes called ejectosomes or ejectisomes, which consist of two connected spiral ribbons held under tension. If the cells are irritated either by mechanical, chemical or light stress, they discharge, propelling the cell in a zig-zag course away from the disturbance. Large ejectosomes, visible under the light microsc…

Photosynthetic and osmotrophic cryptophytes have been described; phototrophic species contain plastids with chlorophyll a and c and phycobilins as accessary pigments. Webbrown algae [40], the recently discovered apicomplexan Chromera velia [41] and the all chromalveolate ancestor, red algae [42,43]. The mechanism of NPQ in red algae is still rather enigmatic, we only know that non-photochemical quenching of fluorescence in red algae is a pH-dependent process, precise NPQ locus is not known [42,43].
WebDec 14, 2024 · Cryptophyte algae are well-known for their ability to survive under low light conditions using their auxiliary light-harvesting antennas, called phycobiliproteins. Mainly acting to absorb light where chlorophyll cannot (500−650 nm), phycobiliproteins also play an instrumental role in helping cryptophyte algae respond to changes in light ...
