What is the main function of bee pollen?

The main function of bee pollen is to act as a protein source for the colony. Pollen collected by foraging bees is rich in proteins, fats, vitamins, and minerals, making it essential for the health and development of the bee population, especially for larvae. The protein in pollen is critical for the growth of young bees, as it supports their development into healthy adult workers. Additionally, when combined with nectar, pollen can be converted into “bee bread,” a nutritious food source that sustains the hive.

The other options do not accurately describe the primary role of pollen within the colony. Water is gathered separately by bees from various sources but is not a function of pollen. Nectar, while an important resource, is collected as a carbohydrate source and does not serve the same purpose as pollen. Honey is also produced from nectar and serves as energy storage but does not relate to the function of pollen. Thus, pollen's primary role is indeed as a vital protein source for the colony.
