Which of the following statements are correct about pollination?
(A) Wind pollinated flowers are often very colourful.
(B) In many aquatic plants like water lily, the pollination takes place by insects.
(C) Wind pollination is quite common in grasses.
(D) In most of the water pollinated species, pollen grains are protected from wetting by mucilaginous covering.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B), (C) and (D) Only
(A) Wind pollinated flowers are often very colourful. — False. Wind-pollinated flowers are small and dull; they do not need to attract insects.
(B) In many aquatic plants like water lily, the pollination takes place by insects. — True. In water lily the flowers rise above the water and are pollinated by insects or wind.
(C) Wind pollination is quite common in grasses. — True.
(D) In most of the water pollinated species, pollen grains are protected from wetting by mucilaginous covering. — True.
NCERT Extract:
Pollination – “… Pollination by water is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons. As against this, you would recall that water is a regular mode of transport for the male gametes among the lower plant groups such as algae, bryophytes and pteridophytes. It is believed, particularly for some bryophytes and pteridophytes, that their distribution is limited because of the need for water for the transport of male gametes and fertilisation. Some examples of water pollinated plants are Vallisneria and Hydrilla which grow in fresh water and several marine sea-grasses such as Zostera. Not all aquatic plants use water for pollination. In a majority of aquatic plants such as water hyacinth and water lily, the flowers emerge above the level of water and are pollinated by insects or wind as in most of the land plants.”
