WebNov 16, 2024 · Chloroplasts are the defining organelles of plants and algae, and evolved through endosymbiosis from a cyanobacterial ancestor ( 1 ). They use light energy to convert CO 2 into carbohydrate through photosynthesis and thus play a pivotal role in controlling atmospheric CO 2 levels. WebThe chloroplast is enclosed by a pair of envelope membranes (inner and outer) that separate the interior of the chloroplast from the surrounding cytosol of the cell.
