What does the highest life trait mean 5

It is said that planting trees is addictive, so some people will plant one after another until the day they die, I don't know how many people believe this statement, because the behavior we see is mostly addictive to cutting trees, cutting down one by one, especially precious tree species, until the day they die.

Valuing plant life is even defined as benevolent by Nobel Peace Prize laureate Schweitzer. It is right for a farmer to harvest grass for his livestock in the field, but it is cruel to deliberately trample on a wild flower on the side of the road on his way home. I don't know who will listen to Schweitzer's persuasion and be kind to lowly plants.

But there is a certain characteristic of plants (especially trees) that is precisely the most valuable and can be the teacher of mankind, and that is its "growing slowly", which includes growth and patience, which are the nature of trees. Among human beings, only the very good group of people will develop "growth" and "patience" in the acquired consciousness. Mark.

Twain was once asked "what is the most important creed of man" and said: There is no doubt that it is growth, and we must continue to change ourselves until the end of life. Mark.

Twain was a chauvinist and megalomaniac in his youth. We were a lot like him when we were younger. As we all know, Mark.

Twain later "grew up" into a man who believed in racial and human equality, a man who regarded freedom as the most important value, and a man who resisted all cruelty and short-sightedness with humor and ridicule; Also in middle age, none of us are like him.

Growth can help a person break free from the ugly "cocoon". Unfortunately, we are not plants, we are born to grow, never stop until we die. We can stop growing at a very young age and spend all the rest of our lives beautifying that ugly cocoon.

Trees best interpret the connotation of "growth", one is to regard "growth" as the most essential feature of life, self-denial, self-doubt, self-renewal, can make the "growth" process to the last moment of life. The second point is that growth can only be slow. A small tree can only grow slowly, and pulling seedlings to help it grow will not work, so slow growth is the basic criterion for growing in plants.

In human society, slowness is a scarce element, and you can meet believers who never read the Bible, writers who never write and critics who never dishonest, saviors who never do a small thing and university professors who never sit in their study, critics who never accept new knowledge and speculators who only believe in deception......In one day, you can meet hundreds of people who are humming and running so fast, as if to lead us to the other side of happiness. In fact, it's just a swarm of mosquitoes hovering over a head. Sadly, there doesn't seem to be a head under them hovering.

Let's plant a tree, at least, and look at it often, and see how they grow and start to look like Mark. Twain grows slowly, don't stop.

Do you understand what that means? Hope it helps

What are the basic characteristics of life?

1. Life molecules composed of chemical elements are the material basis of all life activities;

2. Life shows rigorous structure and a high degree of order;

3. Life through metabolism all living organisms are constantly exchanging matter and energy with the outside world;

4. On the basis of metabolic activity, the organism shows growth characteristics;

5. All living things have the characteristics of reproduction, heredity and variation;

6. Organisms show a high degree of adaptability to environmental factors;

7. Organisms show a tendency to evolve and evolve.

Life characteristics are the common characteristics exhibited by all organisms or most organisms, and it is the most important characteristic of life that has the ability to replicate and can transmit genetic information (it also has the ability to mutate) to offspring in the process of replication.

Life is an information system that can record and express information, accumulate information, maintain and transmit information; Life is a dissipative structure that maintains its order by external energy input, life is evolutionary, evolution is achieved through genetic variation in the process of replication, the genetic code is carried by DNA, DNA is produced in some biochemical process of producing proteins from RNA in cells.

At the heart of life is replication and mutation from generation to generation, and all living things pass on trait information to the next generation through the genetic blueprint imprinted in each cell. Each individual's template is different and consists of a series of tiny genes that make up the genetic code, which in turn is made up of fragments of DNA (deoxyribonucleic acid), a very large biochemical substance. By replicating itself in the cell, DNA is also an important medium in the growth process.

It's like a template that produces a new copy of itself, and just like a copy, there are always small errors in the process. These "small errors" are called "variations". Through heredity and mutation, life has completed the connection and evolution, making life step by step from simple to complex, eliminating and selecting to achieve optimization.

One of the most fundamental characteristics of life is energy metabolism. It includes two aspects: material metabolism and energy metabolism. The body absorbs nutrients from the outside world through material metabolism, and at the same time, through decomposition and absorption in the body, the chemical energy contained in it is released and converted into energy that can be used by tissues and cells, and the human body uses these energy to maintain life activities.

Proliferation and heredity are the most basic characteristics of life There are many different organisms on the earth, and they all share the basic characteristics of life, which mainly have the following three characteristics. Metabolism, stress, reproduction and reproduction.

Metabolism is the most basic feature of life. Metabolism includes two aspects: material metabolism and energy metabolism, and material metabolism refers to the exchange of substances between organisms and the external environment and the transformation process of substances in organisms. Energy metabolism refers to the exchange of energy between the organism and the external environment and the transformation process of the energy of the organism, the metabolism of the organism is going on all the time, once the metabolism stops, life is over.

1. Living organisms have a common material foundation and structural basis;

2. Organisms have metabolic effects;

3. Organisms are adaptable;

4. Organisms have growth, development and reproduction;

5. Organisms have the characteristics of heredity and variation;

6. Organisms are adapted to a certain environment and can also affect the environment.

Note: (1) Although it is said that "all have", not every organism has the above six characteristics, but these six are universal. For example, some creatures cannot reproduce (such as mules).

Among them, metabolism is the most basic feature, which is the basis for all other life activities and is common to all life.

2) As for the structural basis, it mainly refers to the cell structure, but the virus does not have a cell structure, and it is only because the virus must parasitize in living cells to carry out life activities normally, so there is the above statement.

3) These six characteristics are summarized from different perspectives, involving different subspecialties of biology, and are a summary and generalization.

1. Life molecules composed of chemical elements are the material basis of all life activities;

2. Life shows rigorous structure and a high degree of order;

3. Life through metabolism all living organisms are constantly exchanging matter and energy with the outside world;

4. On the basis of metabolic activity, the organism shows growth characteristics;

5. All living things have the characteristics of reproduction, heredity and variation;

6. Organisms show a high degree of adaptability to environmental factors;

7. Organisms show a tendency to evolve and evolve.

Metabolism refers to the process of self-renewal through the continuous exchange of matter and energy between living organisms and their surroundings. Metabolism includes two aspects: assimilation and dissimilation. The body continuously ingests nutrients from its surroundings and converts these nutrients into its own substances, a process called assimilation; At the same time, it decomposes and oxidizes its own components and part of the nutrients ingested, releases energy for the needs of its own life activities, and continuously excretes the metabolites produced after the decomposition and oxidation of the substances, which is called dissimilation.

Assimilation and dissimilation are two aspects of the same metabolic process, and they are closely related and indispensable.

Metabolism is the most basic feature of life. Once metabolism stops, life stops. Therefore, all the functional activities of the body are based on metabolism.

A common trait exhibited by all living things or most living things.

It's called life characteristics. The ability to replicate, the ability to pass on genetic information (and the ability to mutate) to offspring during replication is the most important characteristic of life.

There are very many kinds of organisms, the number is very huge, and the life phenomena are very intricate, and some commonalities of organisms, that is, the attributes of life, can be proposed from the intricate life phenomena, which are listed as follows:

1) Identity of chemical composition.

From the perspective of element composition, they are all composed of C, H, O, N, P, S, CA and other elements;

From the perspective of molecular composition, there are many organic molecules such as proteins, nucleic acids, fats, sugars, vitamins and so on. Among them, proteins are composed of 20 kinds of amino acids; Nucleic acids are mainly composed of 4 nucleotides; ATP (adenosine triphosphate) is an energy storage molecule.

2) Strict and orderly structure.

The basic unit of life is the cell, and the various structural units (organelles) within the cell have specific structures and functions. The biological kingdom is a multi-layered, ordered structure. In addition to the cellular level, there are also levels of tissues, organs, systems, individuals, populations, communities, ecosystems, etc.

Each structural unit in each level, such as the organs in the organ system and the various tissues in each organ, have their own specific functions and structures, and their coordinated activities constitute a complex living system. The genetic code of the genetic programming of various organisms is unified, and they all follow the central law of DNA--RNA--protein.

Attributes of life:1uniformity of chemical composition; 2.Strict and orderly structure; 3.Metabolism; 4.irritability and movement; 5.Homeostasis; 6.growth and development; 7.reproduction and heredity; 8.Adapt.

These are from the college textbook General Biology and do not mention that it is the most basic feature. I think the most basic thing is: adaptation.
