Photosynthesis

Introduction
To learn about what is photosynthesis and how does it work. To show the three parts of photosynthesis and important concepts of each one.
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.

Chloroplasts' main role 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 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.
