What is the essence of life What is the essence of life?

The essence of life lies in the meaning of life, a person can show off the light of life without concealment in a limited life, but some people can only be like a dim star in a limited life, so the essence of life is not in the length of life, but in their own efforts and contributions in a limited life

The essence of life is existence, without which it will quickly disappear, and there can be no reproduction of species.

I think the first half of Rayxu can be used as a good point of view, but in the second half of the sentence, I can only say that we living matter think that those are non-living matter, and it does not mean that they must not have their own life form.

Maybe there is and we don't know.

Upstairs, you think you're a philosopher?

The essence of life is, of course, the genetic material, that is, DNA

To tell you a fact, if all the DNA of human beings is repaired, the human lifespan can reach 1000 years, and the similarity of the two species is also judged by DNA.

It is a wave confined to a finite space, no different from the non-living matter in the universe.

Life is just the definition of human beings themselves.

Maybe the universe is a living entity.

Planet. Stars can also be said to be alive.

Oxidation reaction phenomena in which organic matter participates in and is controlled.

The essence of life is protein, and protein is the embodiment of life activities and has many functions.

Life is a combination of a large number of organic matter, but the reaction between these organic matter is so coincidental that it forms a cycle, that is, metabolism.

The essence of life is reproduction, simply put, continuation.

The essence of life is actually cells.

I don't know, this question is a big question that human beings always have to ask, and maybe it will never find the answer! Or that humanity is not now IQ enough to get an answer.

From a biological point of view, the essence of life is an organic whole composed of various substances, including ribose, protein, sugar, lipid, etc. The most essential feature of life is metabolism. Life must also be characterized by heredity and self-reproduction.

The connotation of life refers to the existence of a certain number of phenomena such as self-growth, reproduction, feeling, consciousness, will, evolution, interaction and other rich possibilities that naturally appear in the process of development and change of the universe, and can also include the self-replicating amino acid structure produced by biochemical reactions, as well as fungi, bacteria, plants, and animals (humans).

The essence of life is the essence of human beings. From a more "natural" point of view: the essence of life lies in: metabolism; Reproduction; Reproductive differentiation and its additiveness.

The human body is composed of cells, and these cells have to go through the stages of undifferentiated, differentiated, senescent, and die, thus constituting the aging and death of the body's structure and function. The process of cellular senescence is a process of complex physiological and biochemical changes in cells, which is ultimately reflected in changes in the morphology, structure and function of cells, and the main characteristics that senescent cells have:

1. In the aging cells, the water decreases, and as a result, the cells shrink, the volume becomes smaller, and the rate of cell metabolism slows down.

2. In senescent cells, the activity of some enzymes decreases. For example, when melanocytes at the base of a person's hair age, tyrosinase activity in the cells decreases, which can lead to graying of the hair.

3. Pigment in cells will gradually accumulate with cell aging. Due to the increase in the area occupied by lipofuscin in cells, it hinders the communication of intracellular substances and the transmission of information, affects the normal physiological functions of cells, and finally leads to cell aging and death.

4. The intracellular respiration rate of senescence slows down, the volume of the nucleus increases, and the chromatin consolidates and deepens the staining.

5. The permeability function of the cell membrane is changed, which reduces the material transport function.

6. Cells die and decompose, and then are absorbed by other cells.
