Question

Quizplus · Accepted Answer

The green immature seed cones of conifers and inconspicuously colored flowers of grasses indicate that they are wind-pollinated. Wind-pollinated plants do not rely on attracting pollinators since their pollen is carried by the wind directly from one plant to another. The absence of bright colors and fragrances indicate that they do not need to attract pollinators.
