The two main groups of chromalveolates. Introduction: Protists are present in huge numbers and are crucial for maintaining the natural balance of the living world. Different protists have different body structures. Chromalveolates refer to a super-group of protists which originated due to secondary endosymbiosis. In this endosymbiosis, an ancestral cell engulfed a red alga giving rise to chromalveolates.
