Chloroplasts

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars which form the raw material for energy and biomass production in all green plants and the animals that depend on them, directly or indirectly, for food. Chloroplasts also capture light energy and convert it free energy in the form of ATP [w] (adenosine triphosphate) and reduce NADP [w] (nicotinamide adenine dinucleotide phosphate) to NADPH through a complex set of processes called photosynthesis. The word chloroplast is derived from the Greek words chloros which means green and plast which means form or entity. Chloroplasts are members of a class of organelles known as plastids [w] - wikipedia
