Answer: the reason is, if there are colourful, then inserts will be attracted and it will be pollinated by wind, and due to its light weight, it will not stick to the insect body, that’s why wind pollinated flowers are colourless, and are light weight so that they can easily be pollinated….
Why do wind pollinated flowers have no petals?
The flowers which carry wind pollination do not have petals so that the stamen remain exposed to the air which helps in easy dispersal of pollen along the current of the air. Flowers have a very large feathery stigma which helps in trapping the pollen present in the air and then the pollination process occurs.
Why do wind pollinated plants have dull not Colourful flowers?
These types of flowers are small and not so bright, and they seem dull. They don’t have any fragrance also. They have long anthers which are protruding out of the flower to help pollen grains to blow off easily. These flowers can produce a large quantity of pollen.
Are wind pollinated flowers bright and colorful?

Why do wind pollinated flowers have one ovule?
Due to variation in wind speed, the pollen losses are high. So the chances of multiple pollen grains dispersed in stigma are very less. Thus, wind pollinated flowers have single ovule.
Why wind pollinated flowers are small and light?
Pollination is the process wherein the transfer of the pollen grains takes place from the anther of one flower to the stigma of the same flower or to the stigma of the different flower. … Further, these pollens are light in weight, non-sticky and small so that they can be easily carried away by wind.
Why do wind pollinated flowers have long and feathery stigma?
Wind pollinated plants have large flowers with feathery stigma, abundant pollen. This is mainly because this feathery stigma helps plants to easily trap airborne pollen grains.

Which is not a feature of wind pollinated flowers?
The stigma is large feathery protruding outside to catch the pollen grains and confirm the pollination. Anther will produce in large numbers. … feathery inserted stigma: it does not possess wind pollinated character because of feathery stigma is present inside the floral part which may not allow the wind pollination.
Why wind pollinated flowers produce large amount of pollen grains?
In wind pollinated plants the chances of loss of pollen grains are more due to which most of the pollen grains fail to reach the appropriate stigma. So to compensate this loss and increase the chances of pollination the wind pollinated flowers produce large number of pollen grains.
What are the differences between wind and insect-pollinated flowers?
Wind-pollinated plants let their pollen blow in the wind and hope that their pollen grains reach another plant for pollination. Insect-pollinated plants use insects and other animals to carry their pollen grains to other plants.
Why do most flowers have brightly colored petals?
Petals are usually brightly coloured because they attract insects. Flowers produce the sweet smell and bright coloured petals, which increases the chances of pollination. … Flowers provide nectar to insects which results in insects pollinating in exchange.
