Biology Coursework Analysis and Evaluation (transpiration)

Analysis - After doing this experiment, I can see from my graph that a decrease in light intensity reduces the rate of transpiration. This is because when there is a high level of light intensity it starts to evaporate any water and because there was such intense light on the plant at the beginning of the experiment water quickly evaporated. This is also due to the fact that leaf water is also needed to aid …

…would not really change my results. I think that if I were to continue my investigation to go for a further 10cm or 20cm that my results would be repetitive because I have covered the total range that the light could carry. When the lamp is so far away the light intensity wouldn't really differ between 10cm so there would be no point in continuing the experiment past the range that I had already chosen.
