1

What 3 limiting factors of photosynthesis?

Light intensity, CO2 concentration and temperature.

2

How does light intensity affect the rate of photosynthesis?

Increasing the light intensity will increase the speed of photosynthesis.

3

How does carbon dioxide concentration affect the rate of photosynthesis?

Photosynthesis can be limited by the concentration of CO2 in the air, even with enough light a plant cannot photosynthesis if there is insufficient CO2.

4

How does temperature affect the rate of photosynthesis?

If too cold or too hot, rate of photosynthesis decreases

5

How can you enhance the conditions in greenhouses to gain the maximise rate of photosynthesis?

Use artificial lights so photosynthesis can continue beyond daylight hours, or a higher than normal light intensity.
Use of paraffin lamps (when burning) produces heat and CO2, so increases photosynthesis.
