Question

How is pollination brought about in maize?
A. by insects
B. by bats
C. by wind
D. by water

Answer 1

Pollination is the act of transferring pollen grains from the male anther of the flower to the female stigma. The goal of every living organism including plants is to create offspring for the next generation one of the ways that plants can produce offspring is by making seeds.

Complete step by step answer: Anemophily or wind pollination is a form of pollination where pollen is distributed by wind. Almost all gymnosperms and anemophilous as many plants in the order poales including grasses, sedges and rushes. Maize that is also called corn in some parts of the world is pollinated by wind. The male anther let go of their pollen and it blows over to a nearby female flower on another plant. Most of the flowers are either male or female on a corn plant(monoecious) Rather than both sexes in one flower(hermaphrodite). Maize flowers have evolved over time ,that is they have changed over time to use wind for pollination. They do not need pretty petals. The pollen is light so it can blow around and the ends of the female parts that are stigma are fluffy to catch all the tiny pollen grains.
So, the correct answer is “Option C”.

Additional Information: Pollination is defined as the deposition of pollen grains on the stigma of flowers. From anthers belonging to the same flower same plant or different plant pollination is of two types
-Self pollination
-Cross pollination
When stigma receives pollen grains from the same flower or same species it is known as self pollination. When stigma receives pollen grains from flowers on the same plant of a different plant There are two forms under cross pollination.
-Pollination by wind
-Pollination by insects
When wind takes male anther of a plant to the female stigma is known as wind pollination. When insects take male anther to the female stigma it is known as insect pollination. Example of wind pollination is gymnosperms, example of insect pollination is rose.

Note: Pollination is a part of sexual reproduction in plants; it describes how the pollen grains get to the female parts of the plant. pollen grains which contain the male gametes need to get to where the female gamete. Maize follows wind pollination. As in case of males. Pollen grain is brought to the female stigma with the help of wind.
