Why can t the earthworm die, how many sections can the earthworm cut before it dies

It's not that you can't cut it to death, and it's definitely not okay to chop it into minced meat.

Rather, the earthworm is relatively low, the regeneration ability of the organs is relatively strong, and when the cut segment is suitable and the environment is suitable, each part of it will develop into a new individual.

Because it is a annelid. You're definitely cutting it horizontally, and if you cut it vertically, it's going to die!

There's a lot of heart, I've heard of it.

Summary. Dear, I'm glad to answer your <>

It is difficult to say that the earthworm will be inactivated when cut into several sections, the internal structure of the earthworm is repeated and repeated, depending on how you cut the earthworm, just cut to its heart, then both sections can not live, if it is cut to the part that separates the repeats, then both sections can live, if it is cut off from the place near the back end, only the front end can generate a complete earthworm.

Earthworms are cut into several pieces before they die.

Dear, I'm glad to answer your <>

Earthworm cut 4 sections to die earthworm is difficult to say cut into several sections will be inactivated, the internal structure of the earthworm is repeated and repeated, see how you cut the earthworm, just cut to its heart, then both sections can not live Tong Annihilation, if just cut to the part that separates the repeat, then both sections can be auspicious wheel wax live, if it is cut off from the place near the back end, only the front end can generate a complete earthworm.

Related information: Earthworms, also known as earthworms, are terrestrial invertebrates of the phylum Oligochaetidae. Earthworm is one of the annelids, there are more than 3,000 species of earthworms in the world, and there are more than 200 species in China.

There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country. Earthworms are rich in nutrition, reproduce rapidly, eat miscellaneous habits, and have high yield in artificial breeding. Good economic benefits.

Earthworms can be used as a valuable medicine** for many diseases, and can also be used as high-protein food and feed. Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, eliminating public pollution, protecting the ecological environment, in material cycle, biodiversity, etc. Earthworms contribute to the material circulation and energy transfer of soil processes through activities such as feeding, digestion, excretion (vermicompost droppings), secretion (mucus) and burrowing, and are one of several soil invertebrate glider groups (mainly earthworms, mites and ants) that have an important impact on the processes that determine soil fertility, and are known as "ecosystem engineers".

The earthworm can only die after cutting it into several sections, and this cannot be judged for the following reasons:

1. It is difficult to say that the earthworm will be inactivated when cut into several sections, the internal structure of the earthworm is repeated and repeated, depending on how you cut the earthworm, just cut to its heart, then both sections can not live, if it is cut to the part that separates the repeats, then both sections can live, if it is cut off from the place close to the back end, only the front end can generate a complete earthworm.

2. Earthworms themselves are eukaryotic cell organisms, to be precise, they may not necessarily grow into two, earthworms are a relatively advanced one of the phylum Annelids, the structure is more complex than many annelids, and the digestive system and circulatory system appear, which is the premise for the development of vertebrates. If there is too much blood loss during cutting, it may not be able to become two, and there are many external factors that can affect its growth.

3. If it is under the conditions of temperature, pH and sterilization, it is possible to survive, just like the tissue culture of plants, of course, cutting off earthworms and tissue culture is not a principle, but the lower the expression of the organism, the greater its ability to develop into an independent individual.

<> reasons: 1. Earthworms, like geckos, contain biological organs in their bodies: regenerative organs, this kind of organ can make earthworms regenerate after being decomposed, if this organ is destroyed, maybe earthworms can not regenerate, after earthworms are decomposed, they secrete a yellow sticky substance to wrap the wound, so earthworms can live again.

2. If the earthworm is truncated into two sections, the muscle tissue on the section will immediately strengthen the contraction, and a part of the muscle tissue will quickly dissolve to form a new cell mass. At this time, the white blood cells in the blood collect at the same time on the cut plane, forming a special embolism that allows the wound to close quickly. Its mesodermal cells are very strong.

3. Earthworms have a strong ability to regenerate, after the body is cut off, it will give birth to tissues like embryos in the broken place, and soon compensate for the lost part and grow into a new earthworm.
