Why do plants not die of cancer? Will produce any type of new cells

Chernobyl has become synonymous with disaster.

 Recently, the hit of a film of the same name. Chernobyl, brought the nuclear disaster that took place in 1986 back to the public eye. The disaster has caused tens of thousands of people to suffer from cancer. Turning a once densely populated area into a ghost city and setting up a restricted area of ​​2,600 km2.

Chernobyl’s restricted area is not without life.

  However, Chernobyl’s restricted area is not without life. The animals of wolves, wild boars and bears have returned to the dense forest around the old nuclear power plant. When it comes to vegetation. Even the most vulnerable plants that are expose to the outermost are not kill in the first place. Even in the most radiation-stricken areas, the damage vegetation is restore within three years.

  In the most polluted areas, the number of humans. Other mammals, and birds that radiation can kill is many times that of plants. So why are plants so resistant to radiation and nuclear disasters so strong?

  To answer this question, we first need to understand how the radiation from nuclear reactors affects living cells. Chernobyl‘s radioactive material is “unstable”. Because it constantly releases high-energy particles and waves that destroy cell structures or create chemical reactions that attack cell mechanisms.

Most of the damaged parts of the cell are replaceable

  But the vital DNA is an exception. At higher doses of radiation, DNA becomes confusing and cells die quickly. Lower doses alter the function of the cell in a mutated form, causing more imperceptible damage, such as cancerous cells, uncontrolled proliferation, and spread to other parts of the body.

  For animals, this is usually fatal because their cells and systems are highly specialize and inflexible. If the animal’s biological system is imagine as a complex machine. Each cell and organ has its own position and function. And the system works properly only when all parts work together. In the absence of a brain, no heart, or no lungs, human life cannot continue.

  However, plants grow in a more flexible and organic way. Since they cannot move, they have no choice but to choose to adapt to the surrounding environment. Plants do not have a fixed structure like an animal, but gradually form a structure during growth. Whether their roots grow deep and stems grow taller depends on the balance of chemical signals from other parts of the plant. As well as light, temperature, moisture and nutrient conditions.

  Importantly, unlike animal cells, almost all plant cells produce any type of new cell that the plant needs. This is why the gardener can grow new plants by cutting. Sprouting new roots from a previous stem or a leaf.

Plants have the ability to replace damaged or dead cells and tissues more than animals. 

  All of this means that for plants, whether their damage cells are attack by animals or expose to radiation. Plants have the ability to replace damaged or dead cells and tissues more than animals. Although radiation and other types of DNA damage can also cause tumors in plants. But because of the hard and connected cell walls around the plant cells, mutant cells that appear on plants often cannot spread from one site to another like cancer. One part. In most cases, such tumors are not fatal because plants can find ways to bypass these failed tissues.

  Interestingly, in addition to naturally having resistance to radiation. Some plants in the Chernobyl exclusion zone seem to use additional mechanisms to protect their DNA. Altering the chemical composition of cells and making them more resistant. Destroy, if this still doesn’t work, they will also start the repair system. In the distant past. When plants began to evolve early. The natural radiation level of the Earth’s surface was much higher than it is now.So in order to survive. Plants in the restricted area may reuse the adaptability of that period.

  Now, around Chernobyl, life is booming. The number of many animal and plant species is actually more than before the disaster.

Chernobyl has caused tragic losses and greatly shortened human life. 

  You may be amaze at the ability of nature to recover. After all, Chernobyl has caused tragic losses and greatly shortened human life. Radiation also does have a significant detrimental effect on plants and may shorten the lifespan of certain plants and animals. However, if you can supply enough life-sustaining resources and are not fatal, then life will continue to thrive.

  Crucially, the damage cause by the radiation from the Chernobyl. Nuclear disaster is no better than the benefits that humanity can leave in this area. Nowadays, it is basically the largest nature reserve in Europe. This ecosystem has more life forms than before, but the life cycle of each individual is shorter.

  To some extent, the Chernobyl disaster reveals the true extent of our impact on the Earth’s environment. Although the nuclear accident was harmful, its damage to the local ecosystem was much less than the damage to us. In the process of human beings driving themselves out of this region. We have created a space for recovery for nature.
