Final answer:
Pollen is able to float through the air easily due to its small and lightweight nature, as well as its shape and structure.
Step-by-step explanation:
Pollen is able to float through the air easily due to its small and lightweight nature, as well as its shape and structure. Pollen grains are typically small and have a powdery texture, which allows them to be carried by wind currents. Additionally, many pollen grains have surface structures that enable them to stick to pollinators such as bees, increasing their ability to be transported through the air.
