Sugars, which are formed by the plant during photosynthesis, are an essential component of plant nutrition. Like water, sugar (usually in the form of sucrose, though glucose is the original photosynthetic product) is carried throughout the parts of the plant by the vascular system. Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients. Within the phloem, sugars travel from areas of high osmotic concentration and high water pressure, called sources, to regions of low osmotic concentration and low water pressure, called sinks. (Osmotic concentration refers the concentration of solutes, or sugars in this case; where the concentration of solutes is highest, so is the osmotic concentration).
The leading cause of limited water supply is water pollution. As the world goes more and more industrialized, more wastes are produced and are not treated and disposed properly. As we see many of the rivers are already dead due to the waste disposed by factories. Some groundwater sources are also contaminated due to eutrophication and bad sanitation implementation. Human activities are the source of these pollution. Also, water becomes more limited due to the increasing population and needs
