Question

Give reasons for the following.

Maize plant has dry and light pollen grains.

Answer 1

Pollination:

1. Pollination is the process of pollen grains being transferred from a flower's anthers to its stigma.
2. Pollination by wind occurs in flowers of maize, rice, and grasses.
3. Wind-pollinated flowers have dry and light pollen grains so that they can be easily carried by the wind.
4. They produce a large number of pollen grains so that at least some can reach the stigma of the flowers.
5. They have feathery and sticky stigmas to catch the pollen grains from the wind.
