Which one of the following statements is not true?
A. The flowers pollinated by flies and bats secrete food odour to attract them
B. Honey is made by bees by digesting pollen collected from flowers
C. Pollen grains are rich in nutrients. and they are used in the form of tablets and syrups
D. Pollen grains of some plants cause severe allergies and bronchial afflictions in some people
Solution
Each pollen grain is a tiny body of different shape and structure that forms in the male structures of seed-bearing plants and is transferred to the female structures by various methods where fertilisation takes place. Pollen is produced by the anthers of the stamens in flowers in angiosperms.
Complete answer:
Bats are important pollinators of nocturnal flowers including agave, guava, and morning glory in the tropics and deserts. The blossoms are typically huge and white or pale-colored to stand out against the gloomy surroundings at night. The flowers smell robust, delicious, or musky, and they produce a lot of nectar. To accommodate the bat's head, they are naturally broad and wide-mouthed. As the bats search for nectar, pollen coats their cheeks and heads, which is subsequently carried to the next bloom.
By sucking nectar from the blossom with their tongues, they collect a sugary juice known as nectar. They keep it in a special stomach called the honey stomach, which is separate from the food stomach. They return to the hive after they have a full load. That is how bees produce honey.
Because pollen grains are high in nutrients, pollen pills have become popular in recent years as a nutritional supplement. Pollen, on the other hand, can survive extreme temperatures as well as strong acids and alkalis. So far, no enzyme that destroys pollen has been discovered.
Allergic bronchitis occurs when an allergen, or anything to which you are allergic, causes inflammation of the bronchi. Pollen, dust, and mould are examples of airway irritants that can cause symptoms. Almost often, cigarette smoking causes allergic bronchitis.
So, the option B is the correct answer
Note:
Palynology is the science of pollen. Pollen is rarely used as a food or a supplement. It is frequently contaminated by agricultural pesticides as a result of agricultural operations.
