how honey bees help pollenate flowering plants
 
1. A worker honeybee leaves the hive to search for pollen. Honeybees need pollen to make honey. 2. He files to a flower and collect tiny pollen grains from the flower's stamen. He carries the pollen in a "basket" on his hind leg. 3. He files to another flower. Some of the pollen grains shake off and fall on the stigma to the flower. 4. The honeybee carries the rest of the pollen grans back to the hive to feed the young honeybees and the queen. 5. The flower begins to make a seed that will eventually grow into a new flower. 6.Many flowering plants depend on the small honeybee to help them transfer pollen so that new plants can grow into flow that can soon be pollenated again 7. how honeybees help is that when the con to a flower pollen gets on there wings that spread into other flowers that will then turn into new flowers that is like a cycle of flowers.

What happens when a pollen grain reaches the stigma of another flower (cross pollination)?
 
A pollen tube is produced with a flower of the same species and it grows down the style until it reaches the ovule. Fertilization takes place, resulting in a seed.
