The beehive's internal structure is a densely-packed matrix of hexagonal cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the "brood" (eggs, larvae, and pupae).
Artificial beehives serve two purposes: production of honey and pollination of nearby crops. Artificial hives are commonly transported so that bees can pollinate crops in other areas. A number of patents have been issued for beehive designs.
