- Flowers are brightly coloured, scented and secrete nectar.
- Pollen grains are larger, sticky and spiny.
- Pollen grains are fewer in number as they are transported mechanically by insects.

Which of the following is a characteristic of wind pollinated flower?
Wind pollinated flowers must show such kind features like large protruding stigma, feathery sticky stigma without petal, odor and nectar to confirm the pollination and anther produce light and large numbers of pollen grains which can travel long distances with wind.
What are insect pollinated plants?
In general, showy, colourful, fragrant flowers like sunflowers, orchids and Buddleja are insect pollinated. The only entomophilous plants that are not seed plants are the dung-mosses of the family Splachnaceae.
What flowers are pollinated by wind?
Wind pollinating plants release billions of pollen grains into the air so that a lucky few will hit their targets on other plants. Many of the world’s most important crop plants are wind-pollinated. These include wheat, rice, corn, rye, barley, and oats.
Why are wind pollinated flowers not Colourful?
These two agents are light in weight as the air and water cannot carry the heavy pollen. Insects get attracted towards the nectar and flower but here in the wind and the water it does not occur. So, this is the reason why wind pollinated and water pollinated flowers are not colorful and they cannot produce nectar.
Why do wind pollinated plants have drab or dull flowers compare it with insect pollinated plants?
Wind-pollinated flowers tend to have small dull-coloured petals or, in the case of grasses, no petals at all. They don’t need petals, colour, nectar or scent to attract animals. The stigmas of receiving flowers are sticky in order to hold on to pollen carried by passing breezes.
What is meant by wind pollination?
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes.
What is the different in pollen at wind and insect pollination?
The key difference between insect and wind pollination is that the plants that use insect pollination produce colourful, attractive and scented flowers, while the plants that use wind pollination produce small, dull and less attractive flowers. Pollination is the process of transferring pollen from anthers to the stigma of a flower.
What are the disadvantages of wind pollination?
Disadvantages of wind pollination: Wind pollination is a wasteful process as compare to pollination by organisms as not all dispersed pollen get transferred to female flowers or cones. It is also non-directional and causes allergic reactions in people, known as hey fever.
What are the examples of wind pollination?
Wind pollinating plants release billions of pollen grains into the air so that a lucky few will hit their targets on other plants.
How does wind help in pollination?
Wind pollinated plants are adapted to ensure that grains of pollen can easily be carried by the wind from male to female parts of flowers, to ensure fertilization can take place.
