How would light intensity generally affect the rate of photosynthesis?

• Increases the rate, up to a point
• Increases the rate
• Decreases the rate
• No relationship to the rate

Why would temperature affect the rate of photosynthesis?

• Enzymatic activity is usually temperature dependent
• plant cells expand with temp, have greater surface area
• More CO₂ dissolved in the water
• More glucose needed for respiration at higher temperatures

How would the concentration of CO₂ in water affect photosynthesis?

• The higher the CO₂, the greater the rate
• The higher the CO₂, the lower the rate
• CO₂ concentration doesn't affect photosynthesis
• a greater rate of photosynthesis causes higher CO₂ concentrations
