Q:

What are the advantages and disadvantages of self-pollination?

A:

Quick Answer

Self-pollination, also called open pollination, maintains the unique attributes of the representative species but does not offer protection against species extinction and may even cause a species harm by replicating diseases and viruses that are passed on to successive generations. Self-pollination ensures breed and species purity by ensuring that natural seeds are disseminated and repopulated.

Full Answer

The benefits and drawbacks of open pollination are often contrasted to effects of cross-pollination or hybrid pollination, and each form of seed dissemination has its advantages and weaknesses. Plants that reproduce using self-pollination are significantly less expensive for gardeners and farmers to raise and cultivate year after year. Their seeds are carried by winds, birds and bees and regrow year after year without necessitating annual purchases. Self-pollinating plants also have predictable growth patterns and habitat needs. Some are annuals and others perennials, and growers know that each kind has individual watering, sunlight and soil needs. However, self-pollinating plants are not uniform in color and other characteristics, which might make them less appealing to consumers. They are also prone to negative impacts from disease and other environmental hazards, as a batch of infected or poor-quality seeds can make a species weak and may eventually cause the species to die out.

  • 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.

  • Q:

    How does pollination take place?

    A:

    Pollination takes place when bees or other pollinators pick up the pollen from a flower's stamen and transfer it to another flower's stigma as they move from flower to flower. Pollination is not an intentional process, but it is key to the reproduction process of plants and is a crucial part of the ecosystem.

  • 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.
