Jenny Rees 5AY1 5A Investigation The Effect of Light Intensity on the Rate of Photosynthesis Photosynthesis is the process by which green plants use the energy of light to convert carbon dioxide and water into simple sugar glucose, which provides a basic energy source for the plant. Plant photosynthesis occurs in leaves and green stems within specialised cell structures called chloroplasts. Chloroplasts contain molecules of chlorophyll, consisting largely of carbon and hydrogen, it is the pigment, which gives green colour and absorbs the necessary light for photosynthesis. Chloroplasts are found in palisade cells, they have a large surface area, which means there is more change of light hitting a chloroplast. Planning; Prediction I predict that the results from the experiment to investigate the effect of light intensity on the rate of photosynthesis will show that as the light intensity increases the rate of photosynthesis will also increase. This will continue to increase up...
