Investigating the Factors that Affect the Rate of Photosynthesis
Content: · Light intensity- if the light is brighter, then the rate of
photosynthesis increases and visa versa. · Water supply- if a plant cannot absorb enough water, then the rate
of photosynthesis decreases. · Carbon dioxide concentration- if the percentage of carbon dioxide in
the atmosphere increases, so does the rate of photosynthesis. · Temperature- if the temperature increases, then the rate of
photosynthesis also increases, (however, temperatures above 40OC can
damage a plant and photosynthesis stops because the chlorophyll gets
too hot). The factor I will be investigating is light intensity; how it affects
the rate of photosynthesis. The factors I will be keeping constant are: · Water supply- by using same millimetre of water each time. · Temperature- by using a thermometer to make sure the water is at the
temperature each time. · Carbon dioxide- by not adding any thing in the water which increase
the carbon dioxide level, such as Hydrogen carbonate.
