Each creature has its own biological means, and many plants can rely on methods to spread the seeds. The way plants spread seeds can be roughly divided into two categories: one is to use external forces, such as the power of the wind, the power of water, the use of animals and humans, and the power of their own. Specific can be divided into the following. Let's take a look at how plants spread seeds:
1, relying on the power of the wind to spread
Some plants use the wind to spread their seeds and spread them to various places in the southeast and northwest. The plant seeds are characterized by small, light weight that can be suspended in the air and carried away by the wind, such as the seeds of common catkins. If we grab a group to look carefully, we will find some small particles inside, this is the seed of the willow.
2, relying on water to spread
As the saying goes, "Let the mountain eat the mountain, rely on the water to eat water." Plants that are usually grown in water and in marshes, whose seeds are spread by water, carry the seeds to distant places as the water flows to various places. For example, our common lotus root, which is in the shape of an inverted cone, is lighter and can float like a boat on the surface of the water, bringing the seeds everywhere.
3, relying on the carrying of animals and humans
Animals and people also help plants to sown seeds, sometimes we often do it inadvertently. Some of the seeds have bristles and barbs. When they are touched, they stick to the clothes or the fur. When we find that we pick it up and throw it on the ground, it helps the seed to spread. Some plants can also spread the seeds by letting their fruits be very bright, beautiful, sweet and delicious, and can also spread the seeds, such as grapes, cherries, etc.
4, spread by their own power
There is also a kind of seed that relies on its own power to spread seeds, such as our common pods, sesame seeds, etc. After maturity, the peel will burst under the sun's sun, and the seeds will burst out. , scattered to the distance.
Understand the method of plant communication, is it admired for the cleverness of plants? Do you know how many plants are there in the world?
Number of plants
Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, green algae, and lichens. Among the plants such as seed plants, bryophytes, ferns and ferns, it is estimated that there are about 350 000 species in existence. Temperature, humidity, light, and fresh water are the basic needs of plant survival.
Well, I have some understanding of plants, know the way plants are spread, and discover that the intelligence of nature is something we can't match. The beauty of contrasting nature often makes us feel small. I hope everyone can learn more about plant knowledge in the future!
