Plants sow some water content of the knowledge of sowing.

What is the content of the water? What does water do?

In plant sowing, except for some individual plants that rely on water to disperse their seeds, water is a necessary substance for the seeds of other plants in order to grow. There are also a few plants that need water to soften the seed shell first in order to grow and develop better.

For example: 1- Spread by water: coconut and mangrove seeds, coconut and mangrove trees grow on islands, their seeds fell directly into the sea a long time ago and went to **grow to**, mangroves are formed in this way, water is not only a way for them to circulate, but also to make their seed shells soften and better take root and sprout.

2- Necessary substances: ordinary plant seeds, no matter what kind of plant, where it is, water is necessary, without water seeds can not grow, just like people will not drink water will have an accident, for plant water is more important, with the help of water, seeds can better self-growth, absorb nutrients.

3- Softening effect: Before planting certain vegetables, the farmer will soak the seeds in water first, in order to better let the seeds germinate, at this time the role of water is to soften the seed shell, so that the seeds are easier to germinate.

Animal transmission, wind transmission, water transmission, catapult transmission.

1. Spread by water.

Coconut: Spread by water, when the coconut is ripe, the coconut fruit falls into the sea and drifts away with the sea.

Water lilies: The fruits of water lilies sink to the bottom of the water when they are ripe. When the pericarp decays, the seeds covered with a spongy outer seed coat float up and float elsewhere.

2. It is spread by small birds or other animals.

Cherries, wild grapes, wild ginseng: The seeds are eaten by small birds or other animals, and because they cannot be digested, they are excreted with feces and spread in all directions.

Pine nuts: They are taken away by squirrels when they store their winter food.

3. Rely on the wind to spread.

Red-skinned willow: It is the catkins that fly to spread the seeds far away.

4. There are also methods for mechanically disseminating seeds.

Impatiens: The fruit of impatiens will bounce and shoot the seeds in all directions, which is a method of mechanical dispersal of seeds.

There are also many legumes that use mechanical seed dispersal.

What are the methods by which plants disperse seeds.

It is spread by water, such as lotus root and other aquatic plants with the help of water currents and aquatic animals, as is coconutEucalyptus, blue-green algae in the water, water hyacinth, sea beans.

This probably has to be told to someone else.

You are talking about water-borne plants, such as Acantha spinosa, Jade, Ichthyophylla, Tiger's heart, Chessboard Tree, etc., as well as the water chestnut by the river in the southern pond.

Plants that grow in or near water, naturally, rely on water to spread propagules. The coconut is one of the best water travelers in the plant world. The coconut fruit is the size of a volleyball, and the outside of the fruit has a layer of leathery skin, which is not easily permeable to water, and can be immersed in salty and astringent sea water for a long time without being corroded; The middle layer of the fruit is a thick layer of fiber, which is very light and full of air, with this thick layer of fiber, the whole coconut is like a life jacket floating on the water; The inner layer is a coconut shell that is as hard as bone, protecting the "unborn" next generation.

When the coconut is ripe, it falls from the tree, and if it falls into the sea, the tide can carry the coconut hundreds of kilometers away, or even farther, and then wash it up to the shore, where a young coconut tree will start its independent life. In summer, we've all seen lotus pods in lotus ponds, right? They are like a small bowl made of jade, standing upright in the pool, don't look at it is bigger than your fist, if you pinch it with your hand, it can also be held by you in the palm of your hand, the original texture of the lotus pod is as loose as a sponge, it is full of air, and between this loose tissue, there are dozens of lotus seeds embedded.

After autumn, the lotus canopy will be like a sponge boat, carrying its passengers, lotus seeds, floating away on the water. Now we know that the seeds and fruits that are spread by water are always wrapped in a thick, light, air-filled protective layer that allows them to float on the surface of the water and swim with the waves.

Many more plants rely on humans or animals to disperse their seeds or fruits. Some seeds or fruits are so small that when you unintentionally step on them, they stick or get embedded in the seams of your shoes, and they follow as far as you go, and when you pause a little, they fall with dust into new territory. Other plants have all kinds of thorns or hooks on their fruits and seeds, and once a person or animal comes into contact with them, the little ones with hooks and long thorns can firmly hang on to the animal's fur or human clothing and spread far away.

The most common seeds or fruits with hooks and thorns are hyssop, xanthium, stealing clothes, and ghost needle grass.

1. Artificial sowing.

You can freely control the time of sowing, the distance between seeds, and the soil environment required for seeds.

2. Wind propagation.

Whenever the seeds are ripe, once the wind blows, some seeds will flutter in the wind, and where they finally fall depends on the chance between the seeds and the land, and the seeds will sprout here.

3. Animals and birds, all living lower animals spread.

Some birds, ants, and puppies will inevitably take some seeds away when they steal some plants containing seeds, and finally the seeds fall to other places, which also forms a seed dispersal. Therefore, many natural plants cannot be grown by humans, and they are spread through these animals. It is equivalent to helping people complete the task of natural greening and sowing.

Plant sowing methods include hole sowing, sowing and strip sowing. According to the demand for moisture, it can be divided into dry sowing and wet sowing. Some plants can be propagated by some striping, grafting, tillering. For some cross-pollinated plants, pollen or seeds can be spread by insects, winds, and seeds.

What are the methods by which plants disperse seeds.

Summary. Plants that rely on water to disperse their seeds are coconuts, water lilies, etc.

Plants that rely on water to disperse their seeds are coconuts, water lilies, etc.

When the fruit of the coconut tree is ripe, it falls from the tree and drifts away with the sea, and when the tide washes it over the island, new coconut trees grow on the shore.

When the fruit of the water lily is ripe, it will fall into the water and slowly rot, and the seeds covered with the spongy outer seed coat will float up, and the big wisdom will float to other places, and finally sink to the bottom of the boiling water to take root and sprout.
