    Pollination Definition

    Transfer of pollen from anther to stigma.

    Animal Pollination

    Pollination done by insects, birds.

    Wind Pollination

    Pollination by wind.

    Filament's Purpose

    The filament supports and holds the anther in a position that allows for efficient pollen release.

    Style's Connection

    The style acts as a pathway, connecting the stigma to the ovary, allowing pollen to travel down to the ovary.
