Identify the incorrect statement related to Pollination-
1 Moths and butterflies are the most dominant pollinating agents among insects
2 Pollination by water is quite rare in flowering plants
3 Pollination by wind is more common amongst abiotic pollination
4 Flowers produce foul odours to attract flies and beetles to get pollinated
Explanation:
The incorrect statement related to pollination is moths and butterflies are the most dominant pollinating agents among insects. - Bees are the most dominating pollinating agents among insects, followed by flies and beetles. Moth and butterflies are also important pollinators, but they are not as dominant as bees. - Pollination by water is quite rare in flowering plants, occurring in only about \(30 \%\) of genera.

In water hyacinth and water lily, pollination takes place by :
1 Water currents only
2 Wind and water
3 Insects and water
4 Insects or wind
Explanation:
Water hyacinth and water lily are both aquatic plants, but their pollination mechanisms are different. Water hyacinth is pollinated by insects or wind, while water lily is pollinated by insects only. - Water hyacinth flowers are brightly coloured and have a sweet fragrance to attract insects. The pollen grains are light and dry, so they can be easily carried out by the wind. POLLINATION

Which one of the following statements is not true?
1 Pollen grains of some plants cause severe allergies and bronchial afflictions in some people
2 The flowers pollinated by flies and bats secrete foul odour to attract them
3 Honey is made by bees by digesting - pollen collected from flowers
4 Pollen grains are rich in nutrients, and they are used in the form of tablets and syrups
Explanation:
Bees make honey by nectar and pollens. Bees collect pollen and nectar in the spring when most flower and plants are in the bloom. Honey collected in form of nectar by storage of liquid nutrient of plants, its chemical composition basically dextrose, sucrose, fructose, in nature of honey.

Which one of the following may require pollinators, but is genetically similar to autogamy?
1 Xenogamy
2 Cleistogamy
3 Apogamy
4 Geitonogamy
Explanation:
Geitonogamy is a type of pollination in which pollen is transferred from the anther of one flower to the stigma of another flower on the same plant. It is functionally cross-pollination, meaning that it requires a pollinator, such as bee or butterfly to transfer the pollen. However genetically, geitonogamy is similar to autogamy, meaning that the pollen grains come from the same plant. Geitonogamy is a common type of pollination in many plants, including tomatoes, beans, and peas.
