The evolutionary significance of a choanoflagellate. Introduction: Chloroplasts are the organelles that are necessary for photosynthesis. They are found exclusively in plant cells and some cells of algae. They contain the pigment chlorophyll that is used for driving the process as it contains various proteins that convert carbon dioxide into carbohydrate molecules.

The autotrophs are the organisms that can synthesize their food by the process of photosynthesis. They harvest the energy from sunlight and convert it into usable form carbohydrate cause glucose. The autotrophs include plants, some bacteria, and algae. The algae are of three types depending upon the pigment present in their chloroplast. These three groups are Phaeophyceae, Rhodophyceae, and Chlorophyceae. The green algae Chlorophyceae is known to give rise to land plants that are modern-day photosynthetic organisms.
