Effects of light intensity and chlorophyll on photosynthesis.
The experimental apparatus used to determine the effects of light and temperature on photosynthesis. Plot of the dissolved oxygen probe output during the last 5 minutes of a 20 minute incubation of a Posidonia sinuosa plant at a temperature of 23 oc and light intensity of 1020 J.UDOl m-2s-1.
In fact, most of photosynthesis occurs in the chloroplast, Chlorophyll absorbs sunlight so converted to chemical energy during the procedure of photosynthesis. ( Campbell 2008 ) There are two phases for photosynthesis. They are light reaction and dark reaction. First, light energy splits H2O into O and H during the light reaction.
From further away, the light intensity will be less, and therefore light will be a limiting factor, however when we increase the light intensity by moving the source of light closer towards the Elodea, which then means that light cannot be the limiting factor of photosynthesis.

This article will have all you need to know about the Biology IAA coursework on the investigation into the effect of light intensity on the rate of photosynthesis. Yes, another boring IAA exam which makes it vital to have no slip ups in the method, validity, reliability, evaluation or conclusion. Firstly, let’s identify what the independent and dependant variables are: Independent Variable.
Light Intensity's Effect on Photosynthesis Aim: To find out how light intensity will affect the rate of photosynthesis in a piece of Canadian Pondweed. Prediction: I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will.
