Concept explainers
To determine: 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.
To contrast: The characteristic differences between the two main groups of chromalveolates.
Introduction: 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. Chromalveolates are further divided into two main groups, one of which is alveolates and the other is stramenopiles.
