Question

2 ways in which cross pollination is occurred

Answer 1

1. By insects: When a bee, butterfly, etc. try to get the sticky sweet pollen inside a flower, the pollen catches on to the insect, too. Then when the insect goes to the next flower, the pollen in pollinates. Note that this is not on purpose.

    2.  Another way plants are pollinated is by the wind. The wind picks up pollen from one plant and blows it onto another. Note that this is by nature.

I hope that helps! :)
