Summary Introduction

To distinguish: Among alveolates such as dinoflagellates, apicomplexans, and ciliates.

Introduction: Alveolates are referred to as subgroup of protists. 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. Chromalveolates are further divided into two main groups, one of which is alveolates and the other one is stramenopiles.
