The process of photosynthesis is one of the most important processes on Earth. All plants, trees and green vegetation depend on it for food production. However, not everyone understands how it works! This concept map will help you remember all of the steps that comprise this wonderful process.

Stage One: The Sun’s rays hit the chlorophyll in a leaf. This process is called phototropism and it occurs because the light-sensitive pigment, “chlorophyll,” absorbs more of the blue or red wavelengths than infrared waves while reflecting about 50% back to its source. The sun’s energy then begins breaking down water molecules into oxygen gas (O) and hydrogen ions (H). Oxygen gas is released from inside plant cells as a byproduct of photosynthesis during Stage Three. These two gases are used for food by animals on Earth.

Step Two: Photosystem II converts solar power to chemical energy through an intermediate molecule known as NADPH+ H+.

Step Four: Once this takes place.
