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.
Pollen 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.
Pollen and seeds have a very high surface area relative to their mass. The means that they are strongly influenced by air currents and have a very low terminal fall velocity. As a result, they can be kept suspended for a long periods of time by turbulence in the air.

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 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.
How do bats overcome the force of gravity and fly?
Bats are able to fly by generating lift with their wings, using a combination of flapping and gliding. They have strong muscles in their wings that allow them to generate enough force to push against gravity and achieve flight. Additionally, bats are lightweight compared to their wing size, which helps them stay airborne.

What does pollen join with to make seeds?
pollen joins an ovule to make seeds
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
What do flowers produce?
Flowers produce pollen, nectar, and seeds. Pollen is used for fertilization, nectar attracts pollinators for reproduction, and seeds are produced for dispersal and reproduction.
What is inside a pollen cell?
seeds
What the fertilization?
the seeds and embryos and pollen
Why must a flower be pollinated to make seeds?
The ovary in the flower must be fertilised by pollen from the stamen and then seeds can form.
How are pollen cones and seed cones different?
Pollen cones produce and release pollen grains, which are male gametes. Seed cones contain ovules that get fertilized by pollen to develop into seeds. Pollen cones are smaller and produce pollen whereas seed cones are larger and produce seeds.
Can a plant make seeds without pollen?
yes
The part of the pistil that grows when seeds form?
the answer is pollen
What fertilize the ovule?
SEED
Do male palm trees produce seed?
No, male palm trees produce pollen instead of seeds. Pollen is necessary for fertilizing female palm trees, which then produce seeds.
