When a bee goes on a foraging trip they only focus on one type of flower, once they land on one they usually land on top of the anther, or the male part of the flower, which is placed near the top of the flower solely to attracted bees, or other pollinators. Once the bee collects its pollen it will fly off to another flower and land on the stigma, or a portion of the female part of the plant,this transfer can be caused by an insect, water or wind, but most of the time this results in pollination, and production of a fruit or seed
