So we know flowers, we know fruits and vegetables, even some alfalfa in hay that the livestock for the meats that we eat, rely on pollinators, but you've got male and female parts to a plant here, and basically pollinators are attracted to plants for their nectar, and in the process, a bee will visit some flowers and pick up some pollen, or that male kind of sperm counterpart, along the way, and then travel to different flowers, and eventually an apple, in this case, will be produced.
