Chapter 30, Problem 8TYU
The pollen produced by wind-pollinated plants is often smaller than the pollen produced by animal-pollinated plants. A reason for this might be that
- A. wind-pollinated plants, in general, are smaller than animal-pollinated plants.
- B. wind-pollinated flowers don't need large pollen grains because they don’t have to attract animal pollinators
- C. small pollen grains can be carried farther by the wind.
- D. animal pollinators are more facile at picking up large pollen grains.
