Explanation

The text states: 'Plastids are thought to be descendants of cyanobacteria that were engulfed by early eukaryotic cells. The plastid-bearing lineage eventually evolved into red algae and green algae. Other protist groups evolved from secondary endosymbiotic events in which red algae or green algae were themselves engulfed.' The SAR supergroup Stramenopiles, Alveolates, Rhizarians is listed as one of the four supergroups of eukaryotes, and based on the table, it includes diverse protists like Diatoms, Dinoflagellates, and Forams, many of which are known to have obtained plastids via secondary endosymbiosis.
