The chloroplast is where photosynthesis occurs. There are structures inside the chloroplast called thylakoids. These thylakoids are membranes with special proteins on them that carry out the light reactions of photosynthesis. These membranes are stacked (these stacks are called grana) in order to increase their surface area for the light reactions. The light reactions are responsible for producing NADPH and ATP which will be used for the Calvin cycle. Between the membranes of the chloroplasts and the thylakoid membrane lies the stroma. Here is where the Calvin cycle takes place. It is responsible for producing glucose from a series of chemical reactions. Essentially, the chloroplast is responsible for carrying out photosynthesis which converts light energy into usable chemical energy for most life on Earth.

Chloraplast has a few roles. They make food in the form of sugars by using water, carbon dioxide obtained from the air, and energy from the sunlight.
