उत्तर
A plant flowering in Mumbai cannot be naturally pollinated by pollen from the same species in New Delhi because pollen grains cannot travel such long distances to reach distant flowers.
However, if pollen grains are carried artificially, then pollination is possible.
Furthermore, pollen-pistil interaction involves pollen recognition, so even if pollen reaches the flower artificially, compatibility must be there for successful pollination.
