• Temperature
• Rainfall
• Carbon Dioxide

How does temperature affect photosynthesis?

• Increases the rate at which enzymes work
• Gives the plant energy to perform photosynthesis
• Stops certain enzymes that interfere with photosynthesis working

What is a limiting factor?

• The factor which increases the rate of a reaction
• The factor that limits the reaction rate
• The factor that limits the rate at which an enzyme is destroyed

Which of these is an example of how a plant can adapt to lose less water?

• Have a waxy layer on the leaves
• Store water in the petals
• Have leaves spread out 

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
