A. PHOTOSYNTHESIS Photosynthesis n: A process by which green plants and other organisms produce simple carbohydrates from carbon dioxide and hydrogen, using energy that chlorophyll or other organic cellular pigments absorb from radiant sources.
Photosynthesis Plants use light energy (sunlight) to combine carbon dioxide (CO2) and water (H2O) to make simple sugars (C6H12O6) Why is this important to us? We cannot make our own food (glucose or energy) we must get our food from plants. Plants are the first step in the food chain.hotosynthesis Plants use light energy (sunlight) to combine carbon dioxide (CO2) and water (H2O) to make simple sugars (C6H12O6) Why is this important to us?
