Organisms are capable of adapting and influencing the environment7With the exception of viruses, living things are made up of cells.

Our teacher just talked about it.

A living thing refers to a collection of living beings with kinetic energy. So what are the basic characteristics of living beings?

The basic characteristics of living organisms are that they need nutrients for life, can breathe, can remove waste products produced in the body, and can grow and reproduce.

1. Organisms need to continuously obtain nutrients from the outside world to maintain their survival throughout their lives. For example, green plants need to absorb water, inorganic salts and carbon dioxide from the outside world, and produce organic matter such as glucose and starch that they need through photosynthesis.

2. In the process of life, organisms will continue to produce many wastes in the body, and can excrete wastes from the body, such as sweating and urination to excrete wastes.

3. Organisms can grow from small sizes. When an organism reaches a certain stage of development, it begins to reproduce the next generation.

At present, microbial technology has been widely used in various industries, and the reason is that there are many kinds of microorganisms in the environment, fast reproduction, wide distribution, easy to cultivate, and strong metabolic ability, so the extracted dominant strains are used to solve many difficult problems in production. As a class of organisms, microorganisms have their own unique characteristics: (1) There are many types.

According to statistics, there are more than 100,000 kinds of microorganisms that have been discovered, and different types of microorganisms have different metabolism methods and can decompose all kinds of organic substances. At present, both at home and abroad like to use microorganisms to prevent and control public pollution, that is, to use microorganisms to do their best, each to take what they need, and synergistically act on substances with complex structures. (2) Fast reproduction.

Under suitable conditions, E. coli can reproduce one generation in 20 30 min, and 72 generations in 24 hours, and the number of bacteria can reach 4....

1. Organisms are all in metabolism (the most basic characteristic).

2. All living things are stressful.

3. Organisms are adaptable.

4. All living things have growth and reproduction.

5. All living things have heredity and variability.

The cell is the basic unit of sufficient organisms.

Viruses do not have a cellular structure, but they meet the 5 characteristics and they are also living organisms.

Problem description: And the essential difference between living and non-living things?

Analysis: The basic characteristics of living organisms Organisms have a common material basis and structural basis Organisms have metabolic effects Organisms have stress Organisms have growth, development and reproduction Organisms have genetic and mutation characteristics Organisms can adapt to a certain environment and can also affect the environment.

1 Organisms have a strict structure: Except for a few species such as viruses, organisms are made up of cells, which are the structural and functional units of organisms. 2 organisms all have a metabolic role:

All living things are constantly exchanging matter with their surroundings.

2. The basic characteristics of living things.

1) Have a common material and structural basis.

Material basis: proteins and nucleic acids.

Structural basis: It has a cellular structure except for viruses.

b) Both have metabolism.

The exchange of matter and energy between living organisms and the external environment takes place.

3) All are stressful. Outside ** organisms.

Metabolic Basis Reaction.

d) all have growth, development, and reproduction (conceptual, real.

Example). v) all have genetic and variant characteristics (concepts, meanings, and examples).

6) can adapt to and influence a certain environment (e.g., lichens.
