Question

What is a structural adaptation of ornithophilous flowers that helps pollen stick to birds?

Options

• Sticky pollen grains

• Powdery pollen grains

• Hard pollen grains

• Smooth pollen grains

Answer 1

Ornithophilous flowers produce sticky pollen grains that adhere easily to the bird's body. This characteristic ensures that pollen remains attached during the bird's flight to another flower, maximizing the efficiency of pollen transfer and cross-pollination.
