FAQs on Unit-3 Honeycomb - Class 7

1. What is the importance of honeycombs in a beehive?
Ans. Honeycombs play a crucial role in a beehive as they serve multiple purposes. They provide storage space for honey, pollen, and the eggs laid by the queen bee. Honeycombs also provide structural support to the beehive and help maintain its shape. Additionally, they facilitate efficient airflow within the hive, which is essential for regulating temperature and humidity levels.
2. How are honeycombs built by bees?
Ans. Bees construct honeycombs using beeswax, which is produced by special glands on their abdomen. Worker bees chew the beeswax and shape it into hexagonal cells, known as honeycomb cells. These cells are then arranged in a precise pattern, allowing bees to maximize storage space and minimize material usage. The process of building honeycombs requires coordination and collaboration among the worker bees.
3. Why do honeycombs have a hexagonal shape?
Ans. Honeycombs have a hexagonal shape because it is the most efficient shape for storing honey and other bee products. Hexagons have the smallest perimeter for a given area, allowing bees to store more honey in the same amount of wax compared to other shapes like squares or triangles. The hexagonal shape also provides structural stability, as the walls of adjacent cells can share common walls, reducing material usage.
4. How do bees maintain the cleanliness of honeycombs?
Ans. Bees are highly organized and clean creatures, and they take great care to maintain the cleanliness of their honeycombs. Worker bees continuously clean the cells by removing debris, dead bees, and excess wax. They also use propolis, a sticky substance made from tree resin, to seal any cracks or gaps in the honeycomb walls. This meticulous cleaning process ensures a hygienic environment for the hive.
5. What happens if a honeycomb is damaged or destroyed?
Ans. If a honeycomb is damaged or destroyed, bees will immediately start the process of repairing it. Worker bees will collect beeswax and rebuild the damaged cells. This repair work is essential for maintaining the structural integrity of the beehive and ensuring the storage of honey, pollen, and eggs. The bees' ability to quickly rebuild honeycombs showcases their remarkable teamwork and adaptability.
