Answer:
The method variables such as depth of solution, data collection method etc. vary the rate of photosynthesis due to their influence on the variables of light intensity, temperature, carbon dioxide, light quality.
Step-by-step explanation:
During photosynthesis, O2 gas is used and CO2 is produced simultaneously using a light as energy source whose intensity may vary, a solution with different depth varies to provide water and sodium bicarbonate varies to provide dissolved CO2 as the more sodium bicarbonate is added, there is a greater amount of carbon dioxide on it, this will resultin an increase in the speed of photosynthesis.
There is always the possibility of human error in experiment variables which may lead to different measures of the maximum rate on photosynthetic capacity (Amax) or the rate in which leaves are able to fix an amount of carbon dioxide per metre squared per second, for example as μmol m−2 sec−1.
