Make connections: How might having the anther atop a tall filament make it more likely that plants will be pollinated? It gets the pollen grains up higher. That makes it more likely that a visiting insect will pick them up.4. ... When the pollen forms on the stamen, the pistils are not ready to receive it.
When the filament is tall, the anther is more exposed to different pollination agents. There are more chances that pollen grains stick on the animals' and insects' bodies or get blown by winds.
------------------------------
Flowers are reproductive structures in charge of the plant's sexual reproduction.
There are feminine and masculine reproductive structures.
The masculine structures include stamens, which are composed of anthers and filaments.
- The anther produces pollen grains of male sex cells.
- The filament provides support to the anther.
Mature pollen grains are driven to the stigma of the same flower or other flowers for the fertilization process.
Different agents are in charge of this transport: animals, wind, insects, water streams.
When filaments are tall, the anthers are more exposed and not protected by the flower.
So these anthers are more accessible for different agents.
- There are higher chances that insects and animals that visit the flowers take the pollen in their bodies.
- There are more chances that accidental pollination by animals occurs when they get in touch with this pollen and accidentally take it to another flower.
- As the anther is more exposed, the wind can transport pollen easier.
