Gardeners please;?
Answers:    1. Some plants use the help of secure animals or insects, known as pollinators, to transport the pollen of one flower to another flower.
2.Another method used to complete cross-pollination is wind-pollination. Flowers which use wind pollination are usually small, simple and do not produce nectar.
