Can an earthworm become two after being cut into two?

It can be turned into two, and earthworms have the property of splitting and reproducing.

It is better to cut it in the middle, if there is a long one and a short one, the short one may die.

The earthworms were cut off according to different parts to obtain three different body segments with head and tail, head and tail, and head and tail, and were cultured at room temperature and soil conditions to observe their regeneration. The results showed that earthworms had the ability to regenerate from head to tail, but the regeneration ability of earthworms was different in different body segments and different segment lengths. Among them, the tail has the strongest regeneration ability and the fastest regeneration speed, followed by the intermediate segment, and the head is the worst.

Sweat to death, your question is not comprehensive enough, Mi has made it clear how to cut it, if you are cutting the earthworm horizontally) has been said very clearly, but if you are cutting the earthworm vertically, and you have broken it in half from beginning to end, do you say he can still live? Huh

No... Basically... But if the reproductive system of the head is intact, and the digestive system and circulatory system are relatively intact, it should be able to live

No, but the first part can survive if it's long enough.

Yes, of course. Otherwise, why is there a joke that earthworms never worry about no one (earthworms) playing mahjong together? As long as it divides itself into four segments, it's fine.

Of course, the longer each segment after cutting, the better the chance of survival. If an earthworm tries to form an army, the result will be nothing but a mess of flesh.

Yes, the ability of annelids to repair is very strong, but the environment must be suitable

If the end near the head accounts for most of it, then the back section can generally grow, that is, it can survive, while the back section cannot survive.

Earthworms are really capable of reproduction and survival

Brother Earthworm said, "I want to play table tennis. So, it cut itself into two pieces and turned it into two earthworms playing table tennis.

The earthworm brother said, "I want to play mahjong." So, it cut itself into four sections, and turned it into four earthworms playing mahjong.

Is this earthworm really that powerful? Do you have a doppelganger? Listen to me slowly, maybe this will change your original perception.

As we all know, earthworms have the ability to regenerate, so can they make two earthworms? If you make it all four, you can turn it into four earthworms? By analogy, can you make a lot of earthworms by chopping them up?

The answer is really beyond your expectations, its regeneration ability is not at all as strong as the legend, let alone chopping, even if it is two pieces, the earthworm will not turn into two.

It turns out that although earthworms have the ability to regenerate, they can't be cut as much as they want, and they need to be started according to their parts. If the knife falls in the wrong place, the earthworm will die.

For earthworms, the most important thing is not the brain, but the reproductive ring. The reproductive ring is the key part of whether the earthworm has the ability to regenerate, and it is different from humans in that it has a brain and a heart. If its reproductive ring is destroyed, let alone reborn into two earthworms, it will be difficult to save its life.

So where is the reproductive ring located in the earthworm? The body of an earthworm is made up of a circle of links, so it's strange why it's called an earthworm instead of a "link"? It's so graphic to use this word to describe earthworms.

Among all the links, the most important is the 11th-40th link, which hides the reproductive ring of the earthworm. If this part of the earthworm is destroyed, it will surely die.

If you avoid this part and cut off the earthworm, then the one with the reproductive ring will continue to live, while the other part will "die".

See? Once an earthworm is cut off, it can only become one at most. And more likely, one is gone, and when it cuts its reproductive ring, it will die.

The regenerative ability is also related to the environment in which the earthworm lives. It prefers a dark and damp environment, and after being damaged, it needs a certain humidity and oxygen concentration to have a higher probability of survival, and it cannot be taken for granted that it can be broken into two sections and will definitely "regenerate separately".

Now you know, right? There's no way an earthworm can cut itself in two to play ping-pong ball, that's just a joke.

How terrible, I don't know when, and who makes us stubbornly think that an earthworm can be cut into two pieces?

Count carefully, what other natural science knowledge has been misunderstood by us for many years, and quickly correct it, but we can't use false rumors anymore!

It depends on the situation, although earthworms have the ability to regenerate, there are thousands of earthworm species in the world, and the regeneration ability of different species of earthworms is also very different. On the earthworm's body, there is a reproductive ring near the head, and only a section that contains the reproductive ring can grow a new body segment and become a complete individual.

An earthworm has 150 rings and vital organs are in 11-40 nodes, if cut on 11-40 nodes, damage the vital organs, then the earthworm can not survive, if cut in other positions can be regenerated.

When the earthworm is cut into two sections, the muscle tissue on its section immediately contracts, and a part of the muscle quickly dissolves on its own, forming a new cell mass, and at the same time, the white Xunji late blood cells gather on the cut surface, forming an embolism, so that the wound is quickly closed.

The mesoderm cells of the earthworm also have a very strong differentiation ability, and when it is wounded, the undifferentiated original cells that were originally located in the diaphragm in the body cavity quickly move to the wound section and connect with their own dissolved muscle cells.
