Photosynthesis Lab

What is the equation for photosynthesis?

• CO2 + H2O + light --> O2 + Glucose

• Glucose + O2 + light --> CO2 + H2O

• Glucose + O2 --> CO2 + H2O + ATP

• O2 + H2O+ light --> Glucose + CO2

What variables were held constant in this experiment? (variables that stayed the same in both cups)

Check all that apply

• Spinach

• Light

• CO2/ No CO2

• Amount of water

What factors affect the rate of photosynthesis?

Check all that apply
