Anthers produce pollen; the stigma is the receptive surface that can receive it. Physical contact between a visitor and the relevant floral structures can move pollen from anther to stigma. Compatibility, timing and flower biology affect what happens next. The model distinguishes a matching plant type from a different type, while simplifying pollen viability and reproductive details. Nectar rewards and pollen transfer are related interactions, but are not the same process.

Symbolic pollen transfer between simplified flowers; colour is a display label, not a compatibility test in real plants.
What to look for
- Pollen moves from anther to stigma
- A visit can miss the receptive surface
- Pollination precedes fertilisation
Explain what you noticed
A visitor deposits pollen on a different plant species. Does the visit alone prove seeds will develop?
Keep this idea: Transfer to a compatible receptive stigma is a step, not the entire seed-making process.
