Investigating the Factors that Affect the Rate of Photosynthesis
Content: · Light energy from the sun
· Chlorophyll to absorb light energy
· Carbon dioxide from the atmosphere and from respiration in plant
cells
· Water which is absorbed by the roots and transported to the leaves
by the xylem tubes. Photosynthesis can be summarised by the equation: [IMAGE] 6CO2 + 6H2O C6H12O6 + 6O2
The reactants are Carbon dioxide and Water; the products are Glucose
and Oxygen. The factors that affect the rate of photosynthesis are: · 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;
