Science Coursework, Photosynthesis
The aim of this investigation is to find out whether the change in light intensity affects the rate of photosynthesis in pondweed.
I predict that as the light intensity increases by the lamp getting closer to the pondweed then the temperature and the rate of oxygen bubbles and the rate of photosynthesis will increase. Photosynthesis can be explained by using the word and symbol equations which are:
Carbon Dioxide + Water + Light Energy Glucose + Oxygen + Water. The balanced symbol equation is:
6CO + 12H O C H O + 6O + 6H O.
And what happens in these equations is that the water is absorbed through the many root hairs and is used along with the absorption of carbon dioxide in the air all can be used to convert into glucose and oxygen is released into the air to be used by us and other land animals that need it. During photosynthesis green plants transform light energy to chemical energy and use that energy to synthesize organic fuel molecules that can be stored in the form of carbohydrates. Carbon dioxide from the atmosphere provides the carbon source for
