Question

give scientific reason for: 1.the stigma of wind pollinated flowers is feathery 2.pollen are sticky and spiny in insect pollinated flowers 3.pollen are light in wind pollinated flowers

Answer 1

Answer:

Hii

1. Wind pollinated flowers are dependent upon pollen flying in the air to get fertilised , so it is obvious that a sunken stigma or that hidden in other floral whorls has lesser chances of pollination , so nature provided it to be long and feathery so that it can easily trap pollen from the air , unlike insect pollinated ...
2. The following are the characteristics of insect - pollinated flower:1) pollen grains are sticky so that they can easily stick to the insect's body.
3. Wind-pollinated flowers don't need to be attractive to insects, so they are usually small and do not produce nectar or have large colourful petals. The anthers dangle in the breeze, and the pollen is blown away. The pollen grains are very small and light so they are easily carried on the wind.
