What is the energy from the light used to do?

What is produced as a by-product?
Oxygen
What is the word equation for photosynthesis?
Light
CO2+H2O ———————->Glucose+O2
Chlorophyll
What 3 factors affect the rate of photosynthesis?
Temperature, light intensity and carbon dioxide concentration
How does temperature affect the rate of photosynthesis?
It affects the enzymes controlling photosynthesis
How does light intensity affect the rate of photosynthesis?
Increasing the light intensity will increase the rate of photosynthesis
How does carbon dioxide concentration affect the rate of photosynthesis?
Increasing carbon dioxide concentration will increase the rate of photosynthesis
