Pollens are very light; some seeds have a large surface area. In both cases, they won't fall quickly, and can be carried away by the wind.

How do pollen and seeds overcome the force of gravity and fly?
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.
What is the Use of Gravity?
because without gravity there would be no universe as we know it. gravity is what keeps us and everthing else on earth. it is the tendency of objects with mass to be attracted to each other. an objects mass is the amount of material it contains. the bigger the mass of an object, the stronger its force of gravity.
How can you make a seed with parachute fall quicker on the ground?
Well its depending on the MASS of the seed or how many seeds you added to your parachute. But if not, try doing a fair test for you parachute. But you'll never can make a seed drop down quicker. It depends on GRAVITY too. Gravity is invented by Isaac Newton. Many sad the apple drop on his head and he got the idea of gravity, but that was wrong. The apple drop next to him.If this does not help you go to my email. Tristan66ko@hotmail.com
How do bats overcome the force of gravity and fly?
Birds are able to fly because of a variety of specialized adaptations. They have high metabolisms to supply their body with energy. They have lightweight bones. They have feathers, some of which are "flight feathers" that are long, strong, and able to produce lift and act as control surfaces. They also have a bone called the furcula, more commonly known as the "wishbone," in their chest, which is very important for being able to produce the strength and skeletal support needed to flap their wings. The mechanics of flight are not unlike an airplane; the factors of lift, weight, thrust, and drag all interact to allow for controlled flight. By flapping their wings, birds create thrust and lift. They are able to steer by changing the shape and orientation of their wings and tail. They change the shape of their wing between the upstroke and downstroke as they flap to minimize drag on the upstroke and maximize the thrust generated downard on the downstroke, providing both lift and thrust. <><><> When all the feathers in a bird's wings are set in a certain way, so that the air cannot flow through them, the wing takes up a special shape which makes the air flow much faster over the top surface of the wing than it flows below the under-surface of the wing when the bird is gliding through the air. The difference in air-speed between the top and bottom surfaces of the wings gives the wings a "lift" force which can easily counteract the force of gravity. Birds also have very powerful muscles to power their wings, which means they can flap their wings so fast that they can actually take off from the ground and move forward through the air, as well as glide "on" the air. A very important fact is that a bird's wings are made of feathers. The feathers are not just ornaments! A bird can make its set of feathers close tightly together, which, when gliding or flapping, forces the air to flow around their top and bottom wing surfaces to give "lift", or it can make its set of feathers "open up", which allows the air to pass straight through them and, therefore, the wing, which allows the bird to fall under the force of gravity. So, because a bird can set its wing feathers to be in any of a vast number of intermediate positions between "feathers fully open" and "feathers fully closed" - not just feathers fully closed for the start of a "flap" going to fully open before the end of a "flap", as would be necessary whilst flapping to take off - a bird can take off, glide, swoop down, glide again and then rise up again or drop, just as much as it wants to do!
What is 100g of seeds converted to oz?
100 grams is 3.53 ounces.

Do scientists think seeds can sense gravity?
false
What is the main function of seeds?
The seeds are used by plants to overcome the adverse climatic conditions. Seeds are also a means of propagation in plants. The dispersal of plant population is also achieved through seeds.
Method of dispersal for seed plants?
the types are: wind (i.e. dandelions get blown and the seeds fly away), explosion.(i.e pea pods just burst open and the seeds roll about), animal (i.e. animals pick up seeds and they eventually fall off) ,water(i.e. coconuts roll into the water go to different land and split open letting the seeds bury themselves), and gravity (i.e. conquers fall to the ground because the force of gravity pulls it, then the conquers burst open letting seeds roll around and get buried).
Seeds disperse by?
Different seeds disperse by different methods depending on their physical characteristics. They can be dispersed by gravity, wind, water, and animal means.
Can seeds sense gravity?
Most likely. I say that because even humans can sense it.
Examples of seed that is dispersed by wind?
Dandelion seeds Milkweed Maple tree seeds Pine seed (although also largely by gravity) cotton seed
How do plants make their babies?
No. That is a simple question and the answer is obvious. Do you see plants "Giving Birth to seeds?" No. I thought not. Seeds are just there. They fall off when they are ready.
Why do gymnosperms and angiosperms produce pollen and seeds?
The group that produces fruits and vegetables are angiosperms. Gymnosperms produce conifers like cedar and softwoods like pine and fir.
A pollen grain is what?
pollen grains are the powdery pollens in the pollen sacs . Pollen sacs are situated in the anther. For a pistil to develop into a fruit and ovules to mature into seeds, pollen grains must be transfered from anthers to the stigma. This process is called pollination.
What are six ways seeds are scatteres?
wind, animals, gravity, water.... that's all i got sorry
How do seeds develop?
seeds develop by needing these parts the embrayo,seed coat and the endosperm
