What are the methods of seed dispersal
An article on knowledge sharing, introducing the various methods of seed dispersal and the common propagation techniques of green plants and flowers. Let's follow the editor to see the specific content!
In nature, various plants have their own ways of dispersing seeds, some rely on wind and water, some on animals and ejection. What methods do they use to disperse seeds? An introduction to the dispersal methods of 10 plants!
I. What methods do common flowers and plants in nature use to disperse seeds?
1. How do flowers disperse seeds?
Different types of flowers have different methods of seed dispersal. Some rely on water, such as lotus and water lilies; some rely on birds or other animals, such as cherries and persimmons; some rely on mechanical means, such as impatiens; and some rely on wind, such as willows and poplars, so the specific method depends on the type of plant.
2. What is the method of seed dispersal in sunflowers?
Sunflowers disperse seeds with the help of wind and animals. Specifically, after sunflower seeds mature and naturally fall off, they rely on the wind to float to various corners, and they will grow once the environment is suitable. Of course, animals can also drop some seeds while foraging.
3. What plants disperse seeds by wind?
Plants that disperse seeds by wind include dandelions, willows, poplars, maples, pines, elms, and maples. They float to various places with the wind and grow once the environment is suitable.
4. What plants' seeds are dispersed by birds?
The seeds of plants such as cherries, wild grapes, persimmons, apples, and wolfberries are dispersed by birds. Birds eat the fruits of these foods, and the undigested seeds are excreted with their feces, then continue to grow, and the seed dispersal distance gradually increases.
5. What are the five seeds dispersed by water?
The five seeds dispersed by water are coconut trees, lotus, bowl lotus, water caltrop, and chessboard foot. These seeds float to various places with the help of water power and then grow on the shore.
II. What are the methods of seed dispersal in plants? An introduction to the dispersal methods of 10 plants!
There are many methods of seed dispersal in plants, including wind dispersal, water dispersal, elastic dispersal, animal dispersal, and ejection. Here are ten methods of seed dispersal:
1. Method one: Water dispersal
Water dispersal is the process of seed dispersal through water. For example, when coconut fruits mature and fall, they float with the water and are washed ashore by the tide, where they germinate and grow into new coconut trees.
2. Method two: Wind dispersal
Wind dispersal is the process of seed dispersal carried by the wind. The most common example is dandelion seeds, which are very light and can be carried far by the wind. Once they land in a suitable environment, they will germinate and grow.
3. Method three: Elastic dispersal
Elastic dispersal is when the plant seeds, after maturing, are ejected from the fruit by the recoiling action of the fruit skin, similar to a projectile being shot to various places. Common examples include oilseed rape, mustard, peas, soybeans, mung beans, and oxalis.
4. Method four: Animal dispersal
Animal dispersal is when some seeds or fruits grow hairs and stick to animals, such as Cocklebur. Additionally, some animals eat fruits, and the seeds left inside their bodies are not digested and are excreted with their feces, spreading the seeds in all directions.
5. Method five: Self-dispersal
Self-dispersal is when seeds, after maturing, fall directly to the ground or are ejected to other places due to the force of gravity, then germinate and grow, such as hair柿子 and large-leafed榄.
6. Method six: Adhesive dispersal
Adhesive dispersal is commonly seen in seeds of Cocklebur. Because the fruit of Cocklebur has barbs, it easily sticks to people or animals and then falls to other places to germinate and grow.
7. Method seven: Rolling dispersal
Rolling dispersal is when seeds, after maturing, fall on a slope and then roll a certain distance due to their own gravity, where they germinate and grow. Examples include chestnuts and hair chestnuts.
8. Method eight: Mechanical dispersal
MEchanical dispersal is when seeds are ejected in all directions during mechanical harvesting, and then grow, such as in the case of impatiens.
9. Method nine: Human dispersal
Human dispersal is when people save seeds after harvesting them to plant the following year.
10. Method ten: Dropping dispersal
Dropping dispersal is when fruits naturally fall to the ground after maturing, rot, and during the decomposition process, the embryo inside gradually matures and grows.
Summary: There are many methods of seed dispersal in plants, including wind dispersal, water dispersal, ejection, and animal dispersal, totaling ten methods, each with a different method of dispersal.
