Filament

Definition

The filament is the slender stalk part of the stamen that supports the anther in flowering plants. Its primary function is to hold the anther in a position where it can effectively release pollen.

5 Must Know Facts For Your Next Test

1. The filament is an essential component of the stamen, which is the male reproductive part of a flower.
2. Filaments vary in length and thickness depending on the species of flowering plant.
3. Together with the anther, filaments form what is known as the androecium of a flower.
4. In some plants, filaments are fused together, forming structures like staminal tubes.
5. The position and length of filaments are crucial for effective pollination by ensuring that pollen reaches pollinators or directly contacts female reproductive parts.
