How are flower seeds spread?

Answer 1

Seeds are distributed in several ways. They are blown about by the wind, think dandelions. They are moved by water. This could be coconuts. They are ingested by animals to be deposited some where else in feces, think birds. A lot of trees get started this way. Look at all of the weeds that grow around trees! They also get stuck in the fur of animals and end up somewhere else. Think of those annoying burs that get stuck in your socks and stickers that you step on. There are probably other ways, but these are the ones I know of.

Answer 2

1. wind
2. animals
3. insects
4. water

Fruit Seed Spreading

1. Falling
2. People eating the fruit and they fall out.
3. People picking them and throwing them out.
4. Birds picking the seeds and taking them out.

Answer 3

Seeds are spread in various ways. They can be spread by the wind, an explosion, water, and animals.

wind: plants such as dandelions have seeds and when the seeds start to get loose the wind blows them off the plant and away to another spot.


explosion: some plants explode and when they do seeds pop out traveling a distance of at least 1 meter.


water: when seeds are spread by water first they need the wind to get the seeds to the water. the wind carries the seeds until they fall to the ground if a seed doesn't get to the ground it will land on water and could possibly travel over seas before it reaches dry land.


animals: if an animal is being walked as if brushes against plants it will pick up seeds on its coat then as it is running the seeds fall off the animals coat. seeds can also be spread by an animal eating a plant and once it has passed through the animal and has landed on the ground in the animals waste the plant can reproduce.

Answer 4

Most of these ways of spreading seeds you can think of via examples.

1) Gravity! Newton had it right when he thought of gravity via a falling apple. Seeds often fall to the ground along with a pod or fruit. As the saying goes the apple doesn't fall far from the tree, so the distance away from the parent plant is limited by branch spread, ground slope, dirt erosion and fruiting (think rolling apple) that reduce friction.

2) Flight! Some plants by pass friction all together and let their seeds take to the air. The swirling blade of a maple seed, the drifting lace of the dandelion (dent de lion - tooth of the lion); yet other just send there seeds on a missile blast like the mimosa pod upon touch. This is a good place to add that not only to seeds travel through the air, but pollen also can be carried around the world spreading DNA information long distances from the parent plant. The distance seeds and pollen can travel is influenced by climate, wind patterns, weight and shape.

3) Sailing away! Some seeds are moved by water. Dropping in streams drifting miles away, even as far as the ocean. Certain plants like the coconut have the ability to survive a salty voyage and therefore are some of the first the found on tropical storm damaged islands. Cast Away just wouldn't be the same if Tom Hanks hadn't been able to use this tree.

4) Hitching a ride! What did Tom bring to that Island in his pocket or in his digestive track that could have reseeded there? Birds have great flight distances and are know for spreading berries seeds along with their own natural fertilizer. They also can contribute to the spread of invasive weeds and plant; one example being English ivy. Velcro way invented based upon the observation of a barbed see catching a ride on a dogs fur. (Burdock, forget me not) Certainly humans for years have saved, traded and planted seeds...even out into space. One of the oldest living plants from the early Jurassic age, the gingko trees is here because it was saved and distributed around the earth from one area in China.

5) More tricks! So you can see there are more than three ways....gravity, wind, water, and mechanical rides on animals or vehicles (ever seen the signs to wash milfoil off boats?). Since there are more expanded answers in mixed method the list could be much longer. Consider situations like fires which cause pine cones to burst open and then get carried away on firefighter boots (some plants with extreme heat have seed bombs that throw seeds), extreme events like the 1980 Mt Saint Helen's volcano with mud lahars that carry whole forests miles away, or Japan's 2011 tsunami that has debris washing up on the shores of distant countries. They all could be classified in the above categories, but the timeline and distances can be dramatically more. Then we have to consider one last idea while considering timelines in distribution. Just as extreme events can speed up the scale there maybe another scale so slow that we don't even think to see it. P.S. lean closer as I whisper this concept - plants move. Which is not to say they put on a backpack and march, rather roots of trees will grow towards richer soil, the next generation a little bit further that direction. Plants have the ability to chemically communicate with each other and influence the distribution of seed within a grove. So over the 270 million years the gingko has been around the cumulative drift of grow and plant signally had a profound effect not only on the survival of this tree, but also on seed spread. So as a time scale answer seeds may be spread very rapidly or extremely slowly. Now go out and plant something green! Gotta love plants.

Answer 5

There are many ways to spread seeds but once they are in the ground either the wind carries them, birds take them and drop them somewhere else or once they have roots the roots spread

Answer 6

By animals, by wind/water/fire, and by gravity.

Answer 7

Through air, water, birds and mammals

Answer 8

wind
