Which characteristic is typical of pollen from wind-pollinated flowers?

Pollen from wind-pollinated flowers is typically small and light, which allows it to be easily carried by the wind. This characteristic is essential for the plant's reproductive strategy, as these flowers often do not have the benefit of attracting animal pollinators. Instead, they rely on their pollen being dispersed through the air across potentially large distances.

The small size and lightweight nature of the pollen grains help ensure that they can remain airborne for longer periods, increasing the chances of reaching the stigma of another flower of the same species. In contrast, other types of pollen, such as that from insect-pollinated flowers, tend to be larger and may be sticky to facilitate transfer by insects. Additionally, wind-pollinated flowers commonly lack characteristics such as strong scents or bright colors, which are typically associated with attracting pollinators. These adaptations are crucial for the successful reproduction of plants relying on wind for pollination.
