Which of the following is NOT an agent of pollination?

Mold is not an agent of pollination because it primarily reproduces through spores, which are not involved in the transfer of pollen from one flower to another. Pollination specifically requires the movement of pollen grains, which is facilitated by agents such as insects, birds, and wind. Insects, such as bees and butterflies, play a crucial role in transferring pollen while feeding on nectar. Birds can also contribute to pollination as they visit flowers for food, inadvertently carrying pollen with them. Wind is a natural means by which plants release pollen into the air, allowing it to travel to other flowers. In contrast, mold operates outside of this mechanism, focusing instead on reproduction through its spores rather than pollen transfer.
