Chloroplasts are organelles found in plant cells that produce food and energy for the cell. They are the main site of photosynthesis in plant cells and help convert energy from the sun into sugars for the plant.
Chloroplasts have specialized structures that help them produce sugars for the plant. They are protected by a double membrane and contain thylakoid stacks that contain chlorophyll. The chlorophyll soaks up the sunlight for the plant and starts the process of photosynthesis in the chloroplasts. Once photosynthesis has occurred, the final products are sugars and starches that the plant can use for food. Photosynthesis also produces oxygen and water for the environment.
