How do plants disperse seeds?
Today's focus is on introducing how plants disperse seeds and understanding the introduction of green plants and flowers, follow the editor to take a look!
In nature, various plants have their own ways of dispersing seeds, some rely on wind and water, others on animals, ejection, etc. What relies on what to disperse seeds? An introduction to the dispersal methods of 10 plants!
I. What do common flowers and plants in nature rely on to disperse seeds?
1. What do flowers rely on to disperse seeds?
Different types of flowers have different ways of dispersing seeds. 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; some rely on wind, such as willows and poplars, so the specific method of dispersal depends on the type of plant.
2. What is the method of seed dispersal for sunflowers?
Sunflowers disperse seeds by relying on wind and animals. Specifically, when sunflower seeds mature and naturally fall off, they are carried by the wind to various corners, and they will grow when the environment is suitable. Of course, animals can also drop some seeds during foraging.
3. What plants rely on wind to disperse seeds?
Plants that rely on wind to disperse seeds include dandelions, willows, poplars, maples, pines, elms, and maples. They are carried by the wind to various places and grow when the environment is suitable.
4. What plants' seeds are dispersed by birds?
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 distance of seed dispersal gradually increases.
5. What are the five types of seeds dispersed by water?
The five types of seeds dispersed by water are coconut trees, lotus, bowl lotus, water caltrop, and棋盘脚 (Qipan 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, spring dispersal, animal dispersal, ejection dispersal, and ten other methods. The following is an introduction to the seed dispersal methods of ten plants:
1. Method one of seed dispersal in plants: Water dispersal
Water dispersal is the process of seed dispersal through water. For example, coconut fruits, after maturing and falling off, are carried away by water currents and washed ashore, where they take root and grow into new coconut trees.
2. Method two of seed dispersal in plants: Wind dispersal
Wind dispersal is the process of seeds being blown away 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 take root and grow.
3. Method three of seed dispersal in plants: Spring dispersal
Spring dispersal is when the seeds of a plant, after maturing, are ejected from the fruit by the skin curling back upon contact, similar to a projectile being shot to various corners. Common examples include oilseed rape, mustard, peas, soybeans, mung beans, and oxalis.
4. Method four of seed dispersal in plants: Animal dispersal
Animal dispersal is when some seeds or fruits have hair that sticks to animals, such as Cocklebur. Additionally, some animals eat fruits, and the seeds left inside the fruits are not digested and are excreted in the feces, spreading seeds in all directions.
5. Method five of seed dispersal in plants: Self-dispersal
Self-dispersal is when seeds, after maturing, directly fall to the ground or are ejected to other places due to the influence of gravity, then take root and grow, such as hair persimmon and large-leafed pleiospermum.
6. Method six of seed dispersal in plants: Adhesion dispersal
Adhesion dispersal is commonly seen with Cocklebur seeds. Because the fruits of Cocklebur have backward hooks, they easily adhere to people or animals and then fall to other places to take root and grow.
7. Method seven of seed dispersal in plants: Tumble dispersal
Tumble dispersal is when seeds, after maturing, fall on a slope and roll a certain distance due to their own gravity to take root and grow, such as chestnuts and hair chestnuts.
8. Method eight of seed dispersal in plants: Mechanical dispersal
Mechanical dispersal is when seeds are ejected in all directions during mechanical harvesting, such as with impatiens.
9. Method nine of seed dispersal in plants: Human dispersal
Human dispersal is when people save seeds after harvesting them to plant the following year.
10. Method ten of seed dispersal in plants: Drop dispersal
Drop dispersal is when fruits naturally fall to the ground after maturing, rot, and during the decomposition process, the germ inside gradually matures and grows.
In summary: There are many ways in which plants disperse seeds, including wind, water, ejection, and animal dispersal, with each method being different.
