Question

In honeybee, the royal jelly is secreted from which of the following glands?
A.Crop gland
B.Wax gland
C.Pharyngeal gland
D.Salivary gland

Answer 1

Hint: The royal jelly is a secretion by the female worker bees which nourishes the larvae as well as the queen. It feeds all the larvae in the colony irrespective of the sex. Royal jelly is sold as a dietary supplement in humans.

Complete answer:
In a honey bee colony there are three kinds of bees found-the queen, female worker bee and the male drones. The female worker bees produce royal jelly which serves as food for the Larvae. Thus the female bees are called the nurse bees. The hypopharyngeal gland which produces the royal jelly also helps in making the honeycomb. After three days the drones and the worker bees do not feed on the royal jelly. The queen feeds on this substance throughout its development.

Crop gland- The nectar collected from the flowers which is stored in the abdomen of the bee is called the crop.
Wax gland -The worker bees have eight wax producing glands which produces bee wax.
Salivary gland-The honey bee comprises three salivary glands. They secrete water soluble digestive enzymes.

Hence, the correct answer is option (C)

Note: The royal jelly contains water, proteins and simple monosaccharide, fatty acids, 10HDA. It also contains minerals, vitamin B and vitamin C. The royal jelly is used as an alternative medicine called apitherapy. It enhances the collagen production, used as a vasodilatation and also is found beneficial in reducing premenstrual syndrome effects.
