Answer 1

In angiosperms normally on the surface of stigma only intraspecific pollens germinate successfully.

Explanation:

Angiosperms use a specialised chemical recognition system to ensure that only pollen from the same species (intraspecific) germinates on the stigma. This "pollen-pistil interaction" prevents cross-breeding between different species and maintains the genetic integrity of the plant.
