Whether the basic characteristics of an organism are metabolism or growth and reproduction 5

It's metabolism.

The exchange of matter and energy between an organism and the external environment and the transformation of matter and energy in an organism is called metabolism. Metabolism is a general term for all ordered chemical changes in an organism. It includes two aspects: material metabolism and energy metabolism.

Substance metabolism: refers to the exchange of substances between organisms and the external environment and the transformation process of substances in organisms. It can be subdivided into:

Nutrients are ingested from the outside world and transformed into their own substances. (assimilation) part of its own substances are oxidized and decomposed, and metabolic wastes are discharged. Energy metabolism: refers to the exchange of energy between organisms and the external environment and the transformation process of energy in organisms.

It can be subdivided into: stored energy (assimilation).

Release of energy (dissipation).

In the metabolic process, there is both assimilation and dissimilation.

It's metabolism.

Metabolism is a general term for all the ordered chemical changes in the living fines.

Metabolism is the basis for all life activities of living organisms.

Creatures are the six basic characteristics:

1。A common basis of material structure.

2。Metabolism.

3。Growth, development, reproduction.

4。Genetic variation.

5。Stress.

6。Adaptation and influence of the environment.

Among them, "the basis of all life activities" is metabolism, which is the most basic characteristic. But viruses can't do it alone.

In both cases, there is still no conclusive conclusion due to the existence of non-cellular structures such as viruses, viroids, and Nguyen viruses.

Organisms that only discuss the structure of cells are generally considered to be metabolism.

Metabolism is a general term for all the chemical reactions of living cells, and its significance is the basis for all the activities of the organism to assign life to life, and it is the fundamental characteristic of life phenomena

Therefore, the answer is: all living cells are chemically deflushed; Carry out all life activities

Assimilation refers to the transformation of nutrients obtained from the external environment into its own constituent substances, and the storage of changes in the amount of vegetation can be buried, such as green plants produce organic matter through photosynthesis, and animals eat; For example, dissimilation refers to the process of change in which an organism can decompose a part of its own constituent substances, release the energy in it, and excrete the end products of decomposition from the body, such as animal perspiration Animal oxygen inhalation and carbon dioxide excretion belong to metabolism

Therefore, the answer is: green plants produce organic dust through photosynthesis; Animals inhale oxygen and excrete carbon dioxide; Animals perspire

Of course, the ratio of free water is higher than that of bound water, and the larger the ratio, the slower the metabolism; The smaller the ratio, the more vigorous the metabolism.

1.Combine with water.

Definition: This part of the water is combined with other substances in the cell, does not flow freely, and accounts for about the total amount of water in the cell.

Function: It is a structural component of the cell.

2. Free water.

Concept: Refers to water that exists in a free way and can flow freely.

Function: It is a good solvent in the cell, and many kinds of substances are dissolved in this part of the water; It is the liquid environment in which cells live; It is a medium for various chemical reactions within the cell; Directly involved in various chemical reactions within the cell; The free flow of free water also facilitates the transport of cellular matter.

Cell metabolism is fast, the content of free water increases, and the content of bound water decreases, so the proportion of bound water decreases compared with free water.

Cell metabolism is slow, the content of free water decreases, and the proportion of bound water is higher than that of free water.

When the metabolism is vigorous, the free water content in the body will increase.

d The more free water, the more vigorous the metabolism.

Metabolism refers to the exchange of matter and energy between the organism and the external environment and the transformation process of matter and energy in the organism, including assimilation and dissimilation Assimilation refers to the change process in which the organism transforms the nutrients obtained from the external environment into its own constituent substances and stores energy; Alienation refers to the process in which an organism can decompose a part of its own constituent substances, release the energy in it, and expel the end products of decomposition from the body Alienation and assimilation are carried out at the same time

So the answer is: assimilation, alienation.

1. Yeast: heterotrophic facultative anaerobic.

2. Lactic acid bacteria Escherichia coli: heterotrophic anaerobic.

3. Mucormycetes, Aspergillus, Corynebacterium glutamicum, Paramecium, Amoeba: all heterotrophic aerobic 4, Rhodospira: autotrophic and heterotrophic, aerobic.

5. Red sulfur bacteria: autotrophic anaerobic.

Biological metabolic type, learn to judge which metabolic type you belong to.

Unlike Lao Jing's secondary metabolism, primary metabolites are basically the same in every plant. （）

a.Positive omission is accurate.

b.Mistake. Correct Answer: a

That's nothing more than assimilation or alienation.

Assimilation includes three types: autotrophic, heterotrophic, and facultative.

The autotrophic type is also commonly used in photosynthesis, chemosynthesis, and nuclear synthesis proposed in the last two years.

For example, green plants ingest inorganic matter from the external environment, convert it into organic matter through light energy, and store, utilize, and maintain life activities, which is an example and characteristic of photosynthesis type.

The same can be said for other autotrophic types, except that chemical energy uses the energy released by a specific chemical reaction process, while nuclear energy uses radiant energy. This is how organic matter is made.

The heterotrophic type relies on the direct ingestion of organic matter in the external environment to transform it into its own constituent substances, store and maintain its own metabolism. For example, sheep, tigers and other pastoral, predator organisms, but also mushrooms and other saprophytes, roundworms and other parasites, all belong to this category.

Facultative organisms have both autotrophic and heterotrophic characteristics, for example, some sea slugs will feed on seaweed, get their chlorophyll out, and bask in the sun during the day to photosynthesize themselves.

According to the process of alienation, organisms can be divided into aerobic, anaerobic, and facultative anaerobic.

The aerobic type mainly uses aerobic respiration to break down organic matter in the body to release energy. There are two types of this: high aerobic and low aerobic. Low-aerobic organisms are aerobic respiratory, but they are not suitable for survival in the partial pressure of oxygen on the earth's surface.

The anaerobic type can only rely on anaerobic respiration (lactic acid fermentation, alcoholic fermentation, etc.) to decompose organic matter. Growth is generally inhibited in an aerobic environment (although there are some that do not matter).

Facultative anaerobic type is capable of catabolizing organic matter under normal or hypoxic conditions.
