Q:

What is pollination?

A:

Quick Answer

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.

Full Answer

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:

    Where does pollination occur in a flower?

    A:

    Pollination occurs in the stigma of a flower, which is the female reproductive part of the flower. After pollination, the seeds grow in the base of the pistil, which is called the ovule.

  • Q:

    How does pollination differ between angiosperms and gymnosperms?

    A:

    Pollination differs between angiosperms and gymnosperms in that most angiosperms entice animals to carry their pollen from plant to plant, while most gymnosperms rely on the wind carrying their pollen to other plants. There are many wind-pollinated angiosperms and a very few animal-pollinated gymnosperms, however. The methods angiosperms use tend to be more effective at spreading quickly, but gymnosperms, particularly conifers, are generally better adapted to cold or dry environments.

    What is artificial pollination?

    A:

    Artificial pollination is the process of applying pollen to plants that would normally be applied by the insects that pollinate plants. Artificial pollination can be accomplished with the use of a brush to apply the pollen. This is a technique similar to the one biologist Mendel used while studying genetics and inheritance. There are several benefits to artificial pollination, including gaining greater control over the genetic population of the crops.

  • Q:

    What does the stigma do for a plant?

    A:

    On a plant, the stigma is the site where the germination of the pollen grains occur. The stigma sits on the top part of the pistil. Along with the style and ovary, the stigma is part of the flower's structure called the pistil.
