A particular species of plant produces light, non-sticky pollen in large numbers and its stigmas are long and feathery. These modifications facilitate pollination by

A

insects

B

water

C

wind

D

animals

Text Solution

Verified by Experts

The correct Answer is:
C

plants use two abiotic (wind and water) and one biotic (animals ) agent to achieve pollination. Majority of plants use biotic agents for pollination.
Pollination by wind is more common amongst abiotic pollination. Wind pollination requires the light and non-sticky pollen grains so that, they can be transported in wind currents.
They often possess well-exposed stamens (so that the pollens are easily dispersed into wind currents) and large often-feathery stigma to easily trap air-borne pollen grains. Wind pollination is common in grasses.
(i) Pollination by water (hydrophily) is quite rare in flowering plants but accuss in aquatic plants.
(ii) Zoophihy is pollination through the agency of animals.
(iii) Entomophily is the most common type of zoophily through the agency of insects.
