What are the ways plants spread their seeds?
Generally speaking, the ways plants spread their seeds can be divided into two main categories: one is with the help of external forces, such as the power of wind, the power of water, and being carried by animals and humans; the other is by relying on their own strength. Specifically, they can be divided into the following types.
1. Spreading by the power of wind
Some plants use wind to scatter their seeds, spreading them to the east, south, west and north. The seeds of such plants are characterized by being small and light, able to suspend in the air and be carried away by the wind, such as the seeds of the common willow catkins. If we grab a clump and look closely, we will find some small particles inside, and these are the seeds of the willow tree.
2. Spreading by water
As the saying goes, "Those who live near the mountains make a living from the mountains, those who live near the water make a living from the water." Plants that usually grow in water and swamps rely on water to spread their seeds, drifting with the current to various places and carrying the seeds far away. For example, the common lotus root is shaped like an inverted cone and is relatively light, able to float on the water surface like a little boat and carry the seeds everywhere.
3. Being carried by animals and humans
Animals and humans also help plants scatter their seeds, and sometimes we often do this unintentionally. Some seeds have bristles or barbs on their surface, and with a light touch they will stick to clothing or fur. When we notice them and casually pick them off and throw them on the ground, we have helped them complete the spread of their seeds. Some other plants attract animals to come and feed by making their fruits very bright and beautiful, sweet and delicious, which can also achieve the goal of spreading seeds, such as grapes, cherries and so on.
4. Spreading by their own power
There is also another type of seed that relies on its own power to spread seeds, such as the common bean pods, sesame and so on. After they mature, the fruit skin, under the baking of the sun, will burst open with a "pop", and the seeds will shoot out and scatter into the distance.
After learning about the ways plants spread, don't you feel great admiration for how clever plants are? Do you know approximately how many species of plants there are in the world?
The ways plants spread their seeds
The plants around us are also diverse, and many plants are familiar to everyone. But how much do you really know about plants? So do you know what the ways plants spread their seeds are? Which plants are suitable for placing indoors? There are surely still some friends who are not very clear about this, so below the editor will introduce it to everyone, hoping it will be of some help.
The ways plants spread their seeds
The ways plants spread their seeds1. Wind
There are many ways plants spread their seeds, and wind dispersal is very common. When we mention wind dispersal, we think of dandelions, right? Some seeds grow appendages shaped like wings or feathers and fly with the wind. Seeds with feather-like appendages are mostly herbaceous plants, such as yellow cress of the Asteraceae family, while woody plants include willow and kapok, among others.
In addition, some tiny seeds have a relatively large surface area to weight ratio, so the seeds can drift with the wind, like the seeds of the Orchidaceae family. The achene of the Asteraceae plant dandelion, when mature, spreads its pappus like a parachute fluttering in the wind, scattering the seeds far away.
2. Water
Water dispersal is also one of the ways plants spread their seeds, mainly seen in aquatic plants. Seeds spread by water have a waxy surface that does not absorb water, fruit skins containing air chambers, and a specific gravity lower than water, so they can float on the water surface and be spread through streams or ocean currents. The seed coats of such seeds often have abundant fibrous tissue, which can prevent the seeds from rotting or sinking due to soaking and water absorption. Seaside plants, such as the sea putat, Hernandia nymphaeifolia and Indian almond, have typical seeds spread by water.
3. Animals
As for the ways plants spread their seeds, I cannot move, but there is always something that can move, so some plants chose to let animals help them spread. Most of the seeds spread by birds are fleshy fruits, such as berries, drupes and syconia. Birds peck at the seeds of Lauraceae plants and then spit the seeds out. After the fruit is eaten, the seeds pass through the digestive tract and are excreted at random. Plants that rely on birds to spread their seeds are a relatively advanced group, because the distance over which birds spread seeds is the farthest of all methods.
As for dispersal by mammals, most involve medium and large fleshy fruits or dry fruits. Generally speaking, mammals are relatively large in size and need a large amount of food, so they choose some large fruits. For example, macaques like to eat the fruits of the velvet persimmon and the banana, and also help these plants spread.
4. Explosive dehiscence
Explosive dehiscence is also a way plants spread their seeds. In some perennial tumbleweeds, such as the branched knotweed (Polygonum divaricatum), when the seeds on the plant are close to maturity, the base of its stem becomes brittle in texture, and when the weather is dry and a strong wind blows, some part of the stem base breaks away from the root, and the plant rolls around everywhere.
In some annual tumbleweeds, such as the sea lavender (Limonium bicolor), the entire aboveground and underground parts of the plant are pulled out by strong winds together with the roots, leaving their original place and beginning to roll.
Introduction to plants suitable for placing indoors
Which plants are suitable for placing indoors1. Pennywort, pennywort is very easy to keep alive and is suitable for hydroponics. It does not need much fertilizer or nutrients and can be placed by the windowsill or beside the computer. Ordinary tap water is enough to keep it alive. It grows fast, and its leaves are round like copper coins, so it is very beautiful visually.
2. Four-leaf clover, four-leaf clover is a lucky clover and needs soil culture, but it grows surprisingly fast. It is also an easy grass to keep, will bloom, has a very good visual effect, and can also absorb dust and dirt. It can be placed on the balcony and plays a role in purifying the air, so many families quite like this plant.
3. Asparagus fern and small aloe are likewise very popular. Asparagus fern is suitable for placing in the study. Asparagus fern is rather difficult to keep well, but many people like its delicate and graceful beauty, and this is also a very aesthetic expectation. Small aloe is very tolerant of drought and can be placed beside the TV. It does not need frequent attention and watering; watering once a week or once every half a month is enough. It needs a little fertilizer, and the aloe leaves can also be taken off to make a face mask.
Plant sowing methods_What are the ways plants spread their seeds?
Main information: The world is colorful precisely because there is life. Plants are one of the main forms of life and an indispensable kind of organism in nature. How do plants reproduce? What are the ways plants spread their seeds? Let us take a look together.
[Plant sowing methods]
Nature is a very magical world, and every kind of life reproduces and multiplies in its own different way. It is also a normal natural phenomenon for plants to reproduce offspring and continue the species. Below we will introduce one by one the main channels through which plants spread and reproduce.
One spreading method: dispersal by wind
We all know that plants cannot move about freely like people; plants are fixed in place. The most important thing for plant dispersal is relying on wind to reproduce and multiply. The most typical plant is the dandelion. As long as you blow on a dandelion gently, it will drift with the wind, suspend in the air, and scatter to all parts of the world with the wind and take root. Plants that use wind to spread seeds are usually relatively light.
One spreading method: dispersal by water
Plants that usually grow by the water rely on the action of water currents to reproduce and multiply. Plants on the water surface basically use water dispersal, such as the water lily. After the seeds of the water lily mature, they fall into the water, and long soaking causes them to rot. The seed coat inside contains sponge tissue, so it floats up and drifts downstream into the distance.
The coconut that we often use also uses this method. The coconut's fruit skin is very loose and rich in fiber, allowing it to float in water. After the coconut matures and its stem falls off, it drops into the sea and drifts far away with the seawater.
One spreading method: dispersal by animals
Many plants also rely on animals to reproduce and multiply. Some plant seeds have bristles, sticky liquid and so on, which stick to animals' bodies and move with them. There are also common fruit trees and so on; after birds eat the fruit, the pits they leave behind are their seeds.
One spreading method: self-dispersal
In the survival of plants, there are also those that use their own power to reproduce, such as bean pods, garden balsam and so on. After garden balsam and bean pods mature, under the strong sunlight, they automatically burst open and shoot the seeds in all directions.
One spreading method: human dispersal
The fruits we often eat mainly rely on humans to spread them. When the pits are thrown on the ground anywhere, they will automatically sprout and grow. Also, while we are walking, some plant hairs often stick to our legs and fall off wherever we go, and this is also plants spreading seeds.
