Question

Quizplus · Accepted Answer

Pollen grains are a key evolutionary adaptation that allows plants to reproduce without the need for water. Pollen can be transported by wind, insects, or other animals, enabling the fertilization of an egg far from the male parent. This adaptation is crucial for the successful reproduction of seed plants (gymnosperms and angiosperms) in terrestrial environments.
