Chloroplasts, organelles in the cells of certain eukaryotic organisms, house the molecular apparatus for photosynthesis. Bacteria-sized structures, somewhat football-shaped, a few micrometers in size, choroplasts number up to several hundred in cells with high photosynthetic rates, each a separate compartmented structure whose boundary consists of two membranes, the interior of the inner membrane containing a semiliquid matrix, called stroma, suspending a system of membranes, called thylakoids, their membranes embedding molecules of chlorophyll and other pigments that absorb energy from sunlight, the initiating step of the physico-chemical process of photosynthesis.[1] [2] [3] [4] [5]
The domain Eukarya includes chloroplast-containing, photosynthesis-capable organisms in two of its four kingdoms,[6] namely plantae (the plant kingdom) and protista (the protist kingdom), the former including photosynthesis-capable algae, mostly single-celled or colonizing members of the plant kingdom, and the green plants we see all around us. The protista including diatoms, dinoflagellates, euglenids, and other members of the protist kingdom, a mixed group of mostly single-celled organisms.
