Q:

What is a filament of a plant?

A:

Quick Answer

The filament of a plant is a stalk that connects to the anther, both of which comprise the stamen. The anther is responsible for producing pollen, which is necessary for plant reproduction.

Full Answer

The filament and anther are part of the system that is essential for the plant to reproduce. Before a flower bud opens and produces and releases pollen, it is encased in protective leaf-like growths called sepals. When a flower bud opens, its petals typically serve to attract insects and other animals that carry pollen to other plants, thus enabling fertilization. Some flower petals possess scents that draw insects to them.

  • 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.

    How do plants reproduce sexually?

    A:

    According to Biosciences for Farming in Africa, sexual reproduction in plants occurs when pollen from a plant's stamen reaches the stigma of a flower. The pollen contains sperm cells while the stigma holds the corresponding eggs. When the two meet, the sperm cells fertilize the egg, creating an embryonic seed that later germinates into a new plant.

  • 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 are pistils and stamens?

    A:

    The stamen and the pistil are the male and female reproductive parts of a flower. The stamen is the male part of the flower, which produces pollen that contains the male gametes needed for reproduction. The stamen is comprised of an anther and filament. The stalk-like filament supports the anther, which contains four fused chambers named microsporangia.
