Three ways to test the effect of photosynthesis or the process
of photosynthesis are:-
On placing the plant close to the light source it will increase
the speed of the bubbling and on taking it away, the formation of
the bubbles significantly reduces. This is a visual indicator on
understanding the light intensity and how it impacts that rate of
photosynthesis.
The next test that can be done to study the effect of
photosynthesis is by measuring the concentration of oxygen. The
concentration of the oxygen helps in finding out the rate of and
effect of photosynthesis.
Also on the available amount of carbon dioxide which is
essential for production of the food, it helps in finding the
effect of photosynthesis
