Correct answer
A. Pollen grains of many species can germinate on the stigma of a flower, but only one pollen tube of the same sp
Step-by-step solution
More than one pollen tube of the same species can grow into the style. It is frequently found in nature. Insects that consume pollen or nectar without bringing about pollination are called pollen/ nectar robbers. Pollen germination and pollen tube growth are regulated by chemical components of pollen interacting with those of the pistil. Some reptiles have also been reported as pollinators in some plant species.
