Question

Quizplus · Accepted Answer

The green immature seed cones of conifers and inconspicuously coloured flowers of grasses indicate that they are probably wind-pollinated. These plants do not require brightly coloured petals or strong fragrances to attract pollinators since they rely on the wind to carry their pollen from one plant to another.
