WebThe purpose of this experiment was to decide if blue light (wavelengths of 425-475 nm) or red light (wavelengths of 650-700 nm) would produce an increase in photosynthetic rate … WebAdd 20 drops of acetone, and grind up the leaves with the acetone using the pestle. This will release the pigments in the leaf. Using the capillary tube, extract the pigment and drop it onto the centre of the pencil line on the filter paper. Suspend the filter paper with the pigment in the solvent; however, make sure that the liquid level does ...

New study shows how light impacts a plants

WebPhotosynthesis is the process of taking an inorganic form of carbon and transforming it into a storable energy rich organic sugar. In many plants this is the basic energy that fuels many of the processes. This reaction of photosynthesis, however, cannot work without light. The first reaction phase of photosynthesis is called the light dependent ...
