Question

Cross in Maize the pollination is brought about by insect

Answer 1

Corss pollination is when pollen from one plant pollinates flowers on a different plant. With maize, cross-pollination is preferred because it is a monoecious crop with male and female flowers in separate parts of the same plant. So, male part produces a large number of pollen grains, which are then distributed by wind to other female parts of another maize plants.

Thus, Cross pollinated by wind'.
