A bee helps to pollinate a flower from the garden that surrounds Old Main while it gathers the flower’s nectar. Pollination allows for fertilization and sexual reproduction in plants by moving pollen, which contains the male gametes or sperm, from the anthers, where it is formed, to the stigma, where it is germinated and forms a pollen tube. This tube transfers the pollen to the female egg cell, located inside the ovules, where fertilization takes place. Flowers attract insects to act as pollinators with sweet nectar so the plant can reproduce. Some flowers are designed in a way that allows the wind to pollinate it.
