The ‘PQR’ of Water Pollution


photosynthesisPhotosynthesis is a process that is actually very complex and we don’t actually know everything about it yet. It is essentially the conversion of sunlight energy into oxygen and sugar. The importance of this process is somewhat evident in the fact that nearly all life on earth depends on it. Trees and leafs are the most common organisms that springs to mind when ordinary people think of photosynthesis. But photosynthesis is a process that can occur everywhere where a little green pigments called chlorophyll is present. This pigment is what absorbs the sunlight before it is processed and in the end turn out as oxygen.
