What are living things made of, and what are living things made of?

The main thing is the cell, followed by the element (the smaller one is the cuck), as for what these two are composed of, it is up to us to discover.

A single-celled organism is a cell, and a multicellular organism is a cell, and the cells form tissues, then tissues form organs, then systems, and then individuals.

Except for viruses, which do not have a cellular structure, everything else is composed of cells, ranging from single cells to multiple cells. Cells are made up of various organic molecules.

In living organisms, the four major elements of C, H, O, and N are the main elements, accounting for more than 95% of the total number of biological elements, which are necessary for all living things, so the current organisms can be called carbon-based organisms. In addition to the four major elements of C, H, O, and N, organisms also have P, S, K, NA, CA, MG, CL and C, H, O, N together called macro elements, and b, f, si, se, as, i, v, cr, mn, fe, co, ni, cu, zn, sn, mo are called trace elements. At present, all the organisms we know are carbon-based organisms, and no other forms of organisms have been discovered, but with the development of science, we can find the existence of other forms of organisms outside the earth, or even on the earth.

Natural fixed matter is inorganic and is a state of inactive substance. The active life matter is organic, which is derived from a series of physical and chemical reactions of inorganic natural fixed substances in the specific environment of a stable liquid water body (earth), so as to realize the fundamental transformation of inorganic matter to organic matter, and realize the continuous birth and evolutionary survival of the single cell of the most primitive active life substance.

Therefore, living organisms are organic active life substances, which are evolved from inorganic natural fixed substances, and the composition of its substances is the same as the four basic elements contained in natural fixed substances, but the chemical reaction transformation process in the stable liquid water environment will fuse them into a primitive living body to form a single-cell ecological phenomenon of active carbohydrates, and can rely on the continuous birth of a large number of single-cell populations as the basis for evolution at different times. It supports and promotes the natural formation of the Earth's biosphere.

Life is a mode of movement, and it also follows the process of changing from the new to the old, and finally to nothing. The peculiarity of the movement of life lies in the fact that it is more complex and controlled by the brain and nerve center, which can direct the actions of animals through their senses.

The structural basis of living organisms is that, with the exception of a few species such as viruses, living organisms are made up of cells.

All living things are made up of cells, and each cell makes up the organs of our body, and then makes up our body, and each structure is so exquisite.

Organisms are composed of nucleic acids and proteins, nucleic acids as the genetic material of organisms to ensure the continuity of organisms from generation to generation, and proteins are the controlling substances of biological traits.

It is made up of cells, and all living things are made up of cells, some are unicellular organisms, and some are multicellular organisms.

The vast majority of living things (specifically, all living things except viruses) are made up of cells.

All living things are made up of cells, and cells are also the basic units that make up living things, and the role of each cell is different.

Most living things (especially all living things except poisons) are made up of cells.

The root cause of all this is determined by --- genetic information ... A number of cells form a number of tissues, and the tissues form different organs, and the organs are combined into a living system, and the living system constitutes a living organism (except for single-celled organisms, which only have a cellular structure; There is no system for plants).As for the length of life, if it is not an accidental death, it is partly determined by the genetic inheritance of the parents, and there is a gene that can control the synthesis of a hormone, called death hormone, which the body will have before death.

1. Except for viruses, living organisms are composed of cells, and the chemical composition of cells is mainly various compounds that make up cells, including inorganic and organic substances, and there are more than 20 kinds of chemical elements that make up organisms;

2. Cells are the basic structural and functional units of organisms, cells constitute organs, organs form systems, viruses do not have a cell structure, and Sun Pai needs to rely on host cells to reproduce, and life needs cells to perform;

3. Among the large number of elements that make up living organisms, carbon is the most basic element, and the main elements that make up protoplasm are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur, accounting for about 95% of the total amount of protoplasm.

All living things, except viruses, are made up of cells. There are both single-celled and multicellular organisms in nature. Cells are the basic structural and functional units of living organisms. Cells are an indispensable part of the biological world.

Definition Summary. Cell: It is the basic unit of life activities, all organisms (except viruses) are made up of cells, and cells are the basic units that make up organisms. Cell.

Cells have an independent, orderly and self-controlled metabolic system, which is the basic unit of metabolism and function Cells are the basis for the growth and development of organisms.

The cell is the basic structural unit of heredity, and the cell has the totipotency of heredity Without the cell, there is no complete life (the virus must live in the living body) Except for the virus, all other organisms are made of cells.

The seven basic characteristics of biology 1, there is a strict structure 2, there is metabolism 3, growth phenomenon 4, stress 5, reproduction and development 6, genetic variation 7, adaptation to a certain environment can also affect the environment.
