Give an example of how a cell's structure related to its function in the body

Teeth are structures that can change rather readily from one mammalian species to another. The flat surface of a molar, for example, is due to its function in grinding food. Incisors take on different forms. They are used for cutting in herbivores and omnivores. They are modified into tusks in elephants. In rodents, the incisors are used for gnawing.
