How does photosynthesis work?
Photosynthesis can happen in plants because they have chlorophyll. Chlorophyll is the pigment that makes plants green. Chlorophyll captures the Sun's energy and uses it to make sugars out of carbon dioxide from the air and water. The sugars fuel a plant's roots, stems, and leaves so the plant can grow. After plants use the Sun's light to make their own food, plants release oxygen into the air. This oxygen if very helpful because humans and animal need it to breath.
photosynthesis step 1
Capturing energy from sunlight.
photosynthesis step 2
Using energy to make ATP and NADTH.
photosynthesis step 3
Using ATP and NADTH to power the synthesis of carbohydrates from CO2.
