How Do You Test If Chlorophyll Is Present In A Plant?
The green colour of the leaves shows the presence of chlorophyll. So there is no need to conduct an experiment just to show its presence. Yes you may conduct an experiment to show that chlorophyll is the pigment which is essential for photosynthesis by conducting the following experiment. Take a croton plant which has yellow and green Colour patches. Keep it in sun for 3-4 hours and then take out the leaves, mark the green patches and yellow patches, decolorise them and test them for starch ( Photosynthesis > Glucose > starch ) with iodine test. You will find blue coloration in the green patches of the leaves indicating presence of starch by photosynthesis in the green areas only.
