WebThis is because cryptophytes acquired photosynthesis by the process of secondary (i.e., eukaryote-eukaryote) endosymbiosis, having engulfed and assimilated a red algal endosymbiont at some time during their evolutionary past (Archibald and Keeling 2002; Bhattacharya et al. 2003; Gould et al. 2008). ... Greenwood AD (1974) The Cryptophyta in ... WebAbstract. Cryptophytes are an ecologically important group of largely photosynthetic unicellular eukaryotes. This lineage is of great interest to evolutionary biologists because their plastids are of red algal secondary endosymbiotic origin and the host cell retains four different genomes (host nuclear, mitochondrial, plastid, and red algal nucleomorph).

WebSymbiogenesis (endosymbiotic theory, or serial endosymbiotic theory) is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms.
