The hydrogen substituents of a glucose ring may bond to the hydroxyl substituants of another glucose molecule to form long chains of glucose and create water as a byproduct. These can often be in the form of starch or cellulose. Starch is a storage molecule used by plants to store glucose. It can be easily digested by animals because the bonds between the individual glucose molecules are relatively easy to break by adding water. Cellulose has a different and more stable chemical structure, and as such, requires much more energy to break down. Because of its strength and stability, cellulose is used by plants to form the tough outer walls of its cells. Herbivores form symbiotic relationships with bacteria to break down cellulose and provide energy to the animal consuming the cellulose <ref> http://www.mansfield.ohio-state.edu/~sabedon/biol1025.htm </ref>.
