Our world is filled with beautiful plants of all different colors. Green is clearly the most obvious colour, and we know that this is a result of the presence of chlorophyll. We also have learnt that photosynthesis is a vital process which happens so as to create oxygen and glucose, by changing carbon dioxide and oxygen in the presence of energy. Chlorophyll is critical for this process because of how the light energy which allows for this process to occur is trapped in the chlorophyll molecule. These molecules are located in the chloroplasts in the mesophyll layer of leaves, but most prominently in the palisade mesophyll that's the most important photosynthesising tissue. My interest was sparked when I started to think about the role this so called vital chlorophyll plays and whether it is really necessary for photosynthesis to occur to occur in plants. While thinking about this I noticed that chlorophyll results in the green colour in plants as green is reflected by the chloroplast cells and red and blue absorbed, therefore plants which are green and white obviously will not have chlorophyll in the parts that are white, as these parts lack the green colour, meaning that photosynthesis isn't supposed to occur in these areas. It is also crucial to remember that leaves which are wholly red still do photosynthesise but the green pigment is merely masked by carotenoids, and that's why only variegated leaves might be used. The most basic method to actually test this is to check along the lines of leaves which are variegated, meaning they are white and green. Aim - In this investigation I would like to test whether chlorophyll is essential for photosynthesis to occur, by testing for the presence of starch in a photosynthesising variegated leaf...
