... time and in the right order. There are in fact, two different stages of photosynthesis, one light stage and one dark stage. This means that it is much more likely that the reaction will take place as it is broken down into simpler stages. All of the molecules do not, therefore, have to be in the same place at the same time. In the first stage, the light-dependent reaction, the chloroplasts trap light energy and use it's energy to breakdown the water from H2O to just hydrogen and oxygen. The oxygen formed in this breakdown of the water, is the oxygen that is given off as a waste gas. This shows that the amount of oxygen produced should be dependent upon and directly proportional to the light intensity. If there is a lower light intensity, then there will be less energy to breakdown the water, through a process known as Photolysis, ...
