Pollen and many other very small particles do not "overcome" the force of gravity; rather, their light weight and small size allow them to be carried by air currents.
Just as a kite flies in wind, these particles may be lifted upwards, also. Motes of dust, feathers, light seeds with filaments or "wings" attached and small pieces of paper may also be lifted by air or wind.

CoachPollen and seeds are dispersed by wind, water, animals, or self-propulsion to overcome gravity and reach new locations for reproduction. They possess adaptations such as lightweight structures, aerodynamic shapes, or structures that enhance buoyancy to aid in their dispersal. This allows them to travel away from the parent plant and increase the chances of successful reproduction.

How do pollens and some seeds overcome the force of gravity?
Pollen grains and some seeds use mechanisms such as wind, water, or animals to transport them over long distances, which helps them overcome the force of gravity. Structures like wings, hairs, or oils on their surfaces aid in dispersal by providing lift or reducing drag, allowing them to travel away from the parent plant and find suitable growing conditions.
What is the Use of Gravity?
Gravity is a natural force that causes objects with mass to be attracted towards each other. It is responsible for keeping our feet on the ground, holding planets and stars in their orbits, and shaping the structure of the universe. Without gravity, life as we know it would not exist.
What things does the wind helps to move?
The wind helps to move things like sailboats, windmills, kites, and wind turbines. It also assists in dispersing seeds and pollen for plants, as well as in shaping landscapes through processes like erosion.
Why do orange seeds float on sugar water but sink in ordinary water?
Orange seeds float in sugar water because the sugar increases the water's density, allowing the seeds to float. In ordinary water, the seeds sink due to their own density being greater than that of the water.
Why fruits fell down from tree?
Fruits fall from trees due to a combination of factors such as ripeness, gravity, wind, and the natural abscission process. When fruits reach maturity, they release enzymes that weaken the stem attachment, making them more likely to detach and fall to the ground where they can disperse seeds and germinate.
