Answer 👉

Drone bees are male bees, while worker bees are female bees.
Drones are larger in size compared to worker bees.
Drones do not possess stingers, while worker bees have stingers.
Drones do not engage in foraging or other tasks within the colony, while worker bees perform various duties such as collecting nectar, pollen, and building and maintaining the hive.

b.Queen bee and worker bee

Answer 👉

Queen bees are female bees specifically designated for reproduction, while worker bees are also female bees but perform various tasks within the colony.
Queen bees are larger in size compared to worker bees.
Queen bees have a developed reproductive system and can lay eggs, while worker bees are sterile and do not lay eggs.
Queen bees are fed royal jelly throughout their larval stage, while worker bees are fed a mixture of pollen and nectar.

¢. Queen bee and drone

Answer 👉

Queen bees are female bees responsible for reproduction, while drones are male bees.
Queen bees are larger in size compared to drones.
Queen bees have a developed reproductive system and can lay eggs, while drones do not possess the ability to lay eggs.
Queen bees mate with drones during the nuptial flight to fertilize their eggs, while drones mate with the queen bee but do not participate in raising the offspring.

3. Give reason:

a. Honey bee is called a social insect.

Answer 👉 Honey bee is called a social insect because they live and work together in organized colonies or hives. They have a highly developed social structure with specific roles assigned to different individuals, such as the queen, workers, and drones. They communicate and cooperate with each other for tasks like foraging, nest building, and caring for the young.

b. Pasture land is required for bee farming.

Answer 👉 Pasture land is required for bee farming because bees rely on flowers and their nectar as a food source. Pasture lands with diverse flowering plants provide a variety of nectar and pollen for bees to collect. Adequate forage resources in the form of flowering plants ensure the availability of food for the bees and contribute to their overall health and productivity.

c. Drone dies after mating.

Answer 👉 Drones die after mating because their sole purpose is to mate with the queen bee. Once a drone mates with the queen during the nuptial flight, its reproductive organs are ruptured and detached from its body, leading to its death. This behavior ensures genetic diversity within the colony, as drones from different colonies compete for mating opportunities with the queen.

d. Beesare multipurpose insects.

Answer 👉 Bees are considered multipurpose insects because they fulfill various ecological roles and provide several benefits. They are important pollinators, facilitating the reproduction of many plant species and contributing to ecosystem health. Bees also produce honey, beeswax, propolis, and royal jelly, which are used by humans for various purposes. Additionally, beekeeping and bee products contribute to economic activities and industries such as agriculture, food production, and medicine.

4. Answer the following questions:

a. Write the various types of bee found in the hive.

Answer 👉 Various types of bees found in the hive include the queen bee, worker bees, and drone bees.

b. What is the function of the drone bee?

Answer 👉 The function of the drone bee is to mate with the queen bee during the nuptial flight. Drones do not have stingers and are not involved in tasks such as foraging or nest building.

c. If the queen bee dies for some reason, who will control the hive?

Answer 👉 If the queen bee dies, the worker bees will take action to replace her. They can select a few female larvae and feed them with royal jelly to develop them into new queen bees.

d. How does the queen bee control other members of the hive?

Answer 👉 The queen bee controls other members of the hive through the release of pheromones. She produces specific chemicals called queen pheromones that influence the behavior and development of the worker bees. These pheromones help maintain the social structure and coordination within the hive.

e. Write the uses of honey.

Answer 👉 Honey has various uses, including being used as a sweetener in food and beverages, a natural remedy for soothing sore throats and coughs, a ingredient in skincare products, and a preservative due to its antibacterial properties.

f. Describe the structure of the queen bee.

Answer 👉 The queen bee is larger in size compared to worker bees and drones. She has a long abdomen, developed reproductive organs, and specialized glands for producing queen pheromones. Her wings are shorter than the worker bees', and she does not have pollen baskets on her hind legs.

g. Mention the functions of the worker bee.

Answer 👉 The worker bees have several functions, including foraging for nectar and pollen, building and maintaining the hive, caring for the young (larvae and pupae), cleaning the hive, producing beeswax, defending the hive, and regulating the hive temperature.

h. Explain how the division of labour occurs in bees.

Answer 👉 Division of labor in bees occurs through a process called age-based task allocation. As bees age, they transition from one task to another, starting from cleaning the hive, feeding larvae, producing beeswax, guarding the hive, and eventually becoming foragers. This division of labor ensures efficient functioning of the hive and optimal utilization of the colony's resources.

i. Explain the life cycle ofhoney bee with diagram.

Answer 👉 The life cycle of a honey bee includes the stages of egg, larva, pupa, and adult bee. The queen bee lays eggs, which hatch into larvae. The larvae are fed royal jelly by the worker bees and undergo several molting stages. They then spin cocoons and transform into pupae. After the pupal stage, adult bees emerge from the cocoons.

j. Whatis the process called in which a drone is developed froman unfertilized egg?

Answer 👉 The process in which a drone is developed from an unfertilized egg is called parthenogenesis or haplodiploidy. Drones develop from unfertilized eggs, meaning they have half the number of chromosomes compared to the female worker bees or queen bees.

k. When a farmer practises bee farming, then income of other farmers in that locality also increases. Justify your reason.

Answer 👉 Bee farming, or beekeeping, can contribute to the increase in income of other farmers in the locality through the process of pollination. Bees play a crucial role in pollinating flowering plants, including crops. When bees visit flowers for nectar and pollen, they inadvertently transfer pollen between flowers, leading to fertilization and higher crop yields. This benefits farmers by increasing the quantity and quality of their agricultural produce.

l. Due to the problem of pasture land in the beekeeping area, beekeepers shifted the bees from there. After that, - there was areduction in the yield of mustard crops of nearby farmers. Based on this, explain the relationship between beekeeping and agricultural production.

Answer 👉 The problem of pasture land in the beekeeping area and the subsequent reduction in the yield of nearby mustard crops indicate the close relationship between beekeeping and agricultural production. Bees are important pollinators for mustard plants, and their absence or reduced presence can lead to decreased pollination and lower crop yields. Adequate pasture land with diverse flowering plants is crucial for the foraging and pollination activities of bees, which in turn positively impact agricultural production.
