Question

Quizplus · Accepted Answer

The green color of immature seed cones in conifers and inconspicuously colored flowers of grasses indicate that these plants are wind pollinated. They do not rely on attracting pollinators using bright colors or strong fragrances. Wind pollinated plants produce light and small pollen grains that are easily carried by the wind.
