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 latter, the protista, including diatoms, dinoflagellates, euglenids, and other members of the protist kingdom, a mixed group of mostly single-celled organisms.
