Q:

What is pollination?

A:

Pollination is the transfer of pollen grains from a flower’s anthers to the same or another flower’s stigmas. Pollens are moved from flower to flower by pollinators, such as butterflies, bees, beetles, moths, bats and birds. The wind also helps in pollination.

Pollination leads to fertilization, which is the fusion of nuclei in the ovule with nuclei from the pollen grain. After successful fertilization, the flower starts to develop seeds. The production of seeds and fruits is contingent on pollination.

Some plants develop seeds through self-pollination, wherein the same plant possesses both pollen and pistil. Others need cross-pollination, wherein pollen and pistil come from different plants. Most plants need the help of pollinators to move pollen to the pistil.

  • Q:

    What is the difference between pollination and fertilization?

    A:

    Pollination is the process whereby pollen grains move from the anther to the stigma on a flower’s style, while fertilization is the fusion of the male gametes and female egg cells to form a new plant seed. Pollination precedes fertilization and depends on such media as wind, water and insects. Pollination takes place externally, while fertilization occurs in the inside of the flower and does not depend on external vectors.

  • Q:

    What is water pollination?

    A:

    Water pollination occurs when pollen drifts on water to contact flowers directly, thereby allowing certain plants to reproduce. Plants that utilize this type of pollination are water weeds and pond weeds, according to the U.S Forest Service. The technical name of water pollination is surface hydrophily.

  • Q:

    How does pollination occur?

    A:

    Pollination may occur as cross-pollination between plants, or when bees, insects and birds transport and replant pollinated seeds and spores. Pollination takes place naturally in several ways, without human intervention. Some plants have the ability to repopulate among each other via the technique of cross-pollination, although most organisms rely on wind currents or pollinators, such as bees, birds and other insects to complete the process.

  • Q:

    What is wind pollination?

    A:

    Wind pollination occurs when the pollen from flowers is transported by the wind. It is also known as anemophily, and it occurs every day to pollinate crops and trees.
