The phosphate head of a phospholipid is polar while the tail is nonpolar. The head is attracted to water while the tail is repelled by water. This causes the heads to aggregate beside water molecules while the tails form a middle layer. Phospholipids made it possible for the existence of micro-environments that were isolated form an outer environment. In these micro-environments, evolution was able to occur. Transpiration Water molecules are held strongly together via hydrogen bonds. In order for water to evaporate, energy must first go into breaking the hydrogen bonds. As temperature increases, the amount of hydrogen bonds that are broken also increases, allowing transpiration rate to increase. At temperatures above 27⁰C, stomata begin to close to conserve water, leading to a lower transpiration rate. Rabbits
