Pollen grains catch on the sticky surface of the stigma, sprout and produce a tube that grows down the style of the flower and joins with the female cell in the ovary. This joining is called fertilization. After fertilization occurs, seeds develop and the fruit grows. Honeybees are the major natural carriers of pollen. As bees fly from the flowers on one tree to the flowers on others, pollen sticks to their body hairs. The bee rubs off the pollen onto the stigma of the blossoms and moves more pollen from its anthers as it stops over on all of the flower bud on the trees. A honey bee may visit 5,000 flowers a day. Fruit trees planted at homes usually have enough wild bees to pollinate. On the other hand, in commercial orchards, beehives are usually located in the orchard when the trees are blooming to improve pollination and how...
