How does temperature affects photosynthesis rate?

• As temperature increases, photosynthesis rate also increases.

• As temperature decreases, photosynthesis rate also decreases.

• Plants cannot photosynthesis if the temperature is too cold or too hot. 

• All of the statements are true.

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

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

If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of high-energy sugars?

• Sugar production will likely increase.

• Sugars will not be produced.

• The rate of sugar production will decrease .

• Fewer sugars will be produced at first, but then the plant will recover.
