Answer:
Following are the methods used by plants to encourage cross-pollination.
1) Wind: Wind is the agent through which pollen grains of the flower flew in the air and falls on the stigma of another flower.
2) Bees: Bees are also called pollinators because they help in the transfer of pollens from one flower to another flower and causes cross pollination.
3) Water: There are some plants in which cross pollination occurs through water. Pollens drop into the water and transported to another flower through water flow.
