Chapter 3 Biology Outline- ?Water and the Fitness of the Environment? The polarity of water molecules results in hydrogen bonding Water is more extraordinary than people thing because water is everywhere. The unequal ?v? shape of a water molecule makes it a ?polar molecule?. Polar molecules have a positive charge on one side of the molecule and a negative charge on the other side. The polar molecules are attracted to each other (they are like magnets) and that is why water always forms droplets and stays together. Four emergent properties of water contribute to Earth?s fitness for life Cohesion Water molecules stick together due to hydrogen bonding. Cohesion contributes to the transportation of water and dissolved nutrients going against gravity in plants.
