A chloroplast is a type of plastid (a saclike organelle with a double membrane) that contains chlorophyll to absorb light energy. The green chloroplasts in this cell are now a critical part of plant cells, but they evolved from an entirely different organism than the plant cell. The chloroplast is thought to have evolved from a cyanobacterial cell that managed to survive the cell's defenses. We know that multiple membranes surround the organelles too.chloroplast: [noun] a plastid that contains chlorophyll and is the site of photosynthesis — see cell illustration.
