Question 18

Cite various instances of how flowers and the pollination process have "coevolved."

Accepted Answer

Answers may vary. The appearance and aroma of flowers are related to the pollination process. Wind pollinated flowers are not usually very showy, whereas flowers that are insect-pollinated or bird-pollinated tend to be colorful in order to attract their pollinators. Night blooming flowers attract nocturnal animal or insect pollinators. Nocturnal bloomers are not usually very colorful, but do tend to have a stronger aroma to attract pollinators in the dark. Another method of attracting pollinators that has evolved in some plants is the production of nectar in glands near the ovary region. Bee pollinated flowers are usually yellow or blue and have ultraviolet shadings that lead the pollinator to the location of nectar.
