Photosynthesis is important to life on earth because it is the only process that captures 1. energy from the sun and converts it into 2. energy in the form of a sugar called 3. This process that happens in the 4. of a plant cell is consist of two stages. The light dependent reaction takes place in where water molecule splits up with the aid of sunlight resulting to the production of energy molecules called 6. needed for the next stage 7. gas is the by-product of light reaction which goes out from the leaf through the stomata and is absorbed by humans and animals. ATP and NADPH will then enter and fuel up the second stage called 8. that takes place in 9. In this stage 10. an essential gas for plants , is broken down and will undergo a series of processes to produce a sugar molecule called glucose.​
