Question:

Wind pollinated flowers are

Options:

1. small, brightly coloured, producing large number of pollen grains
2. small, producing large number of dry pollen grains
3. large, producing abundant nectar and pollen
4. small, producing nectar and dry pollen

Solution:

Pollination taking place by means of wind is known as anemophily, eg, Zea mays, Cannabis, Pinus, etc. Some features of wind pollinated flowers are - (i) Non-essential whorls such as calyx, corolla and bracts, bracteoles are not showy. (ii) The perianth lobes are undeveloped or reduced and sometimes absent. (iii) Flowers are devoid of scent and nectars. (iv) Plants produce a very large quantity of dusty pollen grains. (v) Pollen grains are dry, very small sized, non-sticky and unwettable These feature are helpful for individuality of pollen grains.
