State
Many angiosperm flower traits — color, scent, nectar, and shape — evolved alongside the sensory and feeding traits of animal pollinators.
Show
A tubular red flower with abundant nectar and little scent matches a hummingbird's long bill, strong color vision, and weak smell.
Watch for
Not every angiosperm relies on an animal pollinator — grasses and many trees rely on wind, forgoing showy flowers.
