The chloroplast is the most important organelle.
Chloroplasts are the source of pretty much all of the world's food and fuel and quite a bit of its oxygen supply and life on earth depends on it greatly. Chloroplast is in all green colored cells of a plant including leaves, green stems, and green parts of a fruit. Example: Green Apple Peeling
A chloroplast is enclosed by two membranes which are called the envelope. Inside are two distinct features, a complex organization of folded and interconnecting membranes called the thylakoids, and a rich fluid filled region called the stroma. The proteins and pigments involved in the light reactions of photosynthesis are located on the thylakoid membranes. The enzymes are in the conversion of carbon dioxide to simple sugars are found in the stroma. Together these reactions convert carbon dioxide and water to sugars and oxygen.
