Water acts as a coolant in organisms when they sweat. Because water has a high amount of vaporization when organisms sweat, it takes heat with it when it evaporates. This makes the organism cooler.
- Water can act as a transport medium because it is cohesive. Because the water can bind to itself, and all the molecules are bonded to one another, it alows for the transport of water against gravity
- ex) transpiration or water being drawn up the xylem, water up a straw
Water is a universal solvent because it can dissolve polar and ionic bonds. In order for reactions to occur, the molecules have to be dissolved. The dissolved molecules can react in the cell because the cell is mainly made up of water, which acts as a medium of metabolic reactions.
