PhotosynthesisPhotosynthesis is the conversion of unusable sunlight energy into usable
chemical energy. Plants live and
grow thanks to photosynthesis. The main reactants of this reaction are the water
and the carbon dioxide. The main products are oxygen and sugar.
The rate of photosynthesis may be limited by light intensity, carbon
dioxide concentration or temperature. During the day, photosynthesis is the main
phenomenon. During the night, plants breathe and use some oxygen. So, the rate
of oxygen must increase during the day and decrease during the night. You are going to study the rate of photosynthesis over 48 hours.
This shows how the Temperature probe and the Oxygen sensor were set up in a flask with Elodea to study the photosynthesis.
