• Photosynthesis is the process by which living plant cells which contains chlorophyll, produce food substances like glucose and starch from carbon dioxide and water by using light energy.

• It provides food for all living beings including animals and humans.

• It provides us oxygen to breathe in by releasing oxygen into the atmosphere.

• Photosynthesis can occur in two phases

• Light Reaction and
• Dark Reaction

• Light reaction traps the energy by using chlorophyll and use that energy in splitting water molecules into hydrogen and oxygen which is called photolysis.

• Dark reaction transfer the hydrogen from NADPH through a series of chemical reactions to combine with carbon dioxide to produce glucose by using energy from ATP
