Chloroplasts /ˈklɔːrəˌplæsts, -plɑːsts/[1][2] are organelles, specialized subunits, in plant and algal cells. Their discovery inside plant cells is usually credited to Julius von Sachs (1832–1897), an influential botanist and author of standard botanical textbooks – sometimes called "The Father of Plant Physiology".
Chloroplasts' main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures theenergy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeingoxygen from water. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, muchamino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from 1 in algae up to 100 in plants like Arabidopsis and wheat.[3]
A chloroplast is one of three types of plastids, characterized by its high concentration of chlorophyll, the other two types, the leucoplast and the chromoplast, contain little chlorophyll and do not carry out photosynthesis.
