What does pH have to do with the rate of photosynthesis?

Will an increase in light intensity result in an even further increase in photosynthesis rate?

• Will an increase in light intensity result in an even further increase in photosynthesis rate? I know it will increase, but will a even higher light intensity cauuse an increase in photosynthesis rate? Is this even possible though? How much can you go til photosynthesis stops reacting to the light intensity?

• Answer:

  Photosynthesis is light dependent. At low light intensities, this may become the limiting factor - one reason why plants grow better outdoors, rather than in the house, and one reason why we recommend the use of light banks if you are trying to grow plants in schools. There is also a level above which photosynthesis cannot take place any faster as other factors become limiting - CO2 level or temperature for instance.
