In order to ensure that seeds will survive, they must be carried away (dispersed) from the parent plant. Some seeds have hooks on them that allow them to attach to animal fur or clothes. Some seeds are able to float in water. Some seeds are light and have wings or thin hairs that allow them to be carried away by wind.

Whence, why is it important for plants to have a method to disperse seeds?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
So too, how is the sycamore seed suited to its method of dispersal? The sycamore has a wing with a large surface area. When the fruit drops off the tree it spins, slowing down in descent. If caught by the wind the seed will be carried away from the parent plant, reducing competition for nutrients, water and light. ... This disperses the seeds away from the parent plant.
Beside that, which is the best method of seed dispersal?
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.
Why do seeds of different types need different agents of dispersal?
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.

Violets, poisonous squirting cucumbers, and touch-me-nots or Impatiens capensis (not to be confused with these touch-me-nots) have an effective way of dispersing their seeds: They burst! The forceful ejection sends the seeds flying as far away as possible from the original plant.
Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals' fur.
Seeds can be scattered in many ways. Some seeds are scattered by the wind, some are carried away by birds and insects, some float in water, others are forced away from the plant by exploding pods, and still others hitchhike on animals and people. An example of a seed that travels by water would be the coconut seed.
- Plant seeds can be dispersed in a number of different ways. Some seeds are transported by wind, and have seeds designed to float, glide or spin through the air. ...
- Many plants also use animals to carry seeds around. These seeds may have handy hooks which attach to an animal's fur.
"There are three parts of a seed." "A bean or seed consists of a seed coat, an embryo, and a cotyledon." "The embryo is the tiny plant protected by the seed coat."
Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks—the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.
Plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Have you ever blown on a dandelion head and watched the seeds float away? This is wind dispersal.
Answer: Plants scatter their seeds in order to insure that they don't grow to close to each other.
In this method of seed dispersal, seeds float away from their parent plant. ... Coconut, palm, mangroves, water lily, water mint, are a few examples of plants whose seed are dispersed by the water. Seed Dispersal by Animal and Birds. There are different ways in which animals and birds disperse the seeds.
The fastest germinating seeds include everything in the cabbage family – bok choi, broccoli, kale, cauliflower etc, and lettuce. The slowest seeds to germinate are pepper, eggplant, fennel, celery, which may take 5+ days. The rest such as tomato, beets, chard, squash, onions, will take about 3 days.
Seed dispersal Some seeds are transported by the wind and are shaped to float, glide or spin through the air. Plants growing near a river may use the flowing water to transport their seeds. Some seed pods are designed to explode and throw the seeds a good distance from the parent plant.
Answer: All seeds cannot be dispersed by seeds as for this they need to be light weight and have hairs or wings so that wind can carry them off. all seeds don't have all these features so they are dispersed by different methods as per their characteristics. seeds dispersed by wind are:- maple,dandelion etc.
Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. This is explosive dispersal. ... As the two halves curl back, suddenly released like a tense spring, they flick out the seeds inside in an explosive manner.
Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have 'winged' seeds. They don't float away but flutter to the ground.
Many violet species exhibit two modes of seed dispersal. ... Often, seeds are then further dispersed by ants through a process called myrmecochory. Violets whose seeds are dispersed this way have specialized structures on the exterior of the seeds called elaiosomes.
