The main role of chloroplasts is to conduct photosynthesis , where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy - storage molecules ATP and NADPH while freeing oxygen 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 , much amino acid synthesis , and the immune response in plants . The number of chloroplasts per cell varies from one , in unicellular algae , up to 100 in plants like Arabidopsis and wheat .
