Characteristics of Stamen
The stamen is a modified leaf-like structure made up of two major parts: the filament and the anther. The filament is a thin stalk-like structure that supports the anther, which is a sac-like structure containing pollen.
There are several types of stamen that can be distinguished based on their physical characteristics, including:
- Perfect stamens: These stamens have both a filament and an anther and are capable of producing viable pollen.
- Imperfect stamens: These stamens won’t consists of filament or anther and can’t produce viable pollen
- Stamens with appendages: Some stamens may have additional structures attached to the filament or anther, such as hairs, scales, or wings.
- Stamens with specialized functions: In some plant species, stamens may have specialized functions beyond pollen production, such as attracting pollinators or providing structural support.
- Fertile and sterile stamens: In some flowers, the stamens may include both fertile (capable of producing pollen) and sterile (non-pollen-producing) structures.
Stamen – Structure, Functions and Types – Biology Class 12
CBSE Class 12 – Sexual Reproduction In Flowering Plants – Stamen: Stamen is the plant reproductive organ. Stamen produce pollen and usually consists of anthers and filaments. The stamen is a key component of the flower, which is the reproductive structure of angiosperms. The stamen’s function is to produce and release pollen, which is then transported to the female reproductive structure of the plant, the pistil, to facilitate fertilization and seed formation. The stamen’s structure and arrangement vary depending on the species of plant, and can be a useful characteristic for plant identification.
