Increasing temperature can increase enzyme activity to a certain point. Then what happens?

• The enzymes have completed all the reactions so stop
• The enzymes have been denatured or destroyed
• Nothing - the rate continues to increase all the time

If a plant receives more carbon dioxide, what happens to the rate of photosynthesis?

• Increases
• Decreases
• Stays the same

How can greenhouses increase the rate of photosynthesis?

• Controlling and trapping heat to increase photosynthesis
• Stopping rainfall affecting plant growth
• Surrounding plants in the colour green makes them more likely to photosynthesise
• Plants are only given what they need instead of just taking everything they can find
