Question

Chlorarachniophytes are believed to have acquired their chloroplasts via endosymbiosis with green algae. The other options (stramenopiles, apicomplexans, and dinoflagellates) have chloroplasts that were acquired through secondary endosymbiosis, where an ancestor of these groups engulfed an algal cell that already had a chloroplast. Therefore, their chloroplasts are not thought to be derived from ancestral green algae directly.
