Explanation:

Both perform photosynthesis led researchers to propose that Chloroplast evolved from Cyanobacteria.

Cyanobacteria are known to be the ancestor of chloroplast and they are also refer to as blue green algae because they contain chlorophyii which is a photosynthetic pigment. The Cyanobacteria are able to perform photosynthesis because of chlorophyii which trap light energy from sunlight and uses carbondioxide and water to produce energy.
