What is the main difference between queen jelly and worker jelly?

The main difference between queen jelly and worker jelly lies in their composition, particularly in the types of sugars they contain. Queen jelly, which is specifically secreted by nurse bees to feed the queen, has a higher concentration of fructose. This is significant because fructose is a simple sugar that can provide energy in a way that supports the rapid growth and high reproductive output of the queen bee.

On the other hand, worker jelly, which is also a food source for worker larvae but not for the queen, has a higher glucose content. Glucose is crucial for the energy needs of worker bees, which are involved in various labor tasks throughout the hive.

This distinction in sugar composition reflects the different roles and requirements of the queen and the workers within the colony, making option B the accurate choice.

The other options either misrepresent the composition of these jellies or state that there is no difference, which contradicts the established knowledge of bee nutrition and the specific needs for the different castes within the hive.
