Final answer:
Photosynthesis is a chemical reaction that converts carbon dioxide and water, using sunlight, into glucose and oxygen.
Step-by-step explanation:
Photosynthesis is a chemical reaction that converts carbon dioxide and water, using sunlight, into glucose and oxygen. The equation for photosynthesis is 6CO₂ + 6H₂O → C6H12O6 + 6O₂. In the process, plants absorb sunlight through the chloroplasts in their leaves and draw water and carbon dioxide from the roots and air.
