This video segment adapted from NOVA explains how flowers play a central role in the reproductive cycle of plants. Their striking array of colors, patterns, fragrances, and nectar all require lots of energy to produce. But it is these features that attract insects and other animals, which, in turn, carry genetic material from flower to flower. The video and illustration describe various parts of the reproductive system, including the stamens and pistil, which generate seeds and ensure the survival of an enormous variety of plant species.
