What does it mean to make up a biological organism?

All living things that have living activities can be called biological organisms, such as bacteria, fungi, animals, plants.

The organic compounds that make up living organisms are: sugars, proteins, nucleic acids, lipids.

Biological organisms are composed of about 40 elements, of which carbon, hydrogen, oxygen, sulfur, and phosphorus are the most important elements, all of which are in the environment and constitute biological individuals and biomes in the ecosystem. Producers convert inorganic matter into organic matter for consumer consumption; The waste generated by consumers and the residues of producers are digested by decomposers and converted into inorganic matter and returned to the environment for plant reuse. There are countless such material cycles on Earth, which converge into the total material cycle of the biosphere.

All living things that have living activities are biological organisms. Such as bacteria, fungi, plants, animals. An organism is a general term for living individuals, including plants and animals, such as the lowest and most primitive single-celled organisms, and the highest and most complex human beings.

Difference Between Organism and Organic Matter:

1. The meaning of the two is different.

Organism, also known as "organism", generally refers to all living organisms that can realize all life activities.

Organic matter is the material basis for the production of life, and all living organisms contain organic compounds. The metabolism of organisms and the genetic phenomena of organisms are involved in the transformation of organic compounds.

2. The content of the two is different.

Organisms include: viruses, prokaryotes, eukaryotic protists, plants, and animals, among others.

Organic matter includes: fats, amino acids, proteins, sugars, heme, chlorophyll, enzymes, hormones, etc.

3. Miscellaneous. Many substances that are closely related to human life, such as oil, natural gas, cotton, dyes, chemical fibers, plastics, plexiglass, natural and synthetic medicines, etc., are closely related to organic compounds.

Viruses are living things because viruses have life.

Virus, like all organisms, has the ability of heredity, mutation, evolution, is a very small size, extremely simple structure of life form, virus has a high degree of parasitism, completely dependent on the host cell's energy and metabolic system, access to the material and energy required for life activities, leaving the host cell, it is just a large chemical molecule, stop moving, can be made into protein crystallization, for a non-living body, encounter the host cell it will be adsorbed, enter, replicate, assemble, The virus is a primitive life form between living and non-living organisms because it releases progeny viruses and shows typical characteristics of living organisms.

A virus is made up of a nucleic acid molecule (DNA or RNA) and a protein or protein alone (e.g., prions). The virus is tiny and has a simple structure. Viruses do not have a cellular structure and cannot replicate on their own because they do not have the basic systems necessary to achieve metabolism.

But when it comes into contact with the host cell, it sheds its protein coat, and its nucleic acids (genes) invade the host cell, and with the help of the latter's replication system, it replicates the new virus according to the instructions of the viral gene.

Biology is a living individual. The most important and basic characteristics of living organisms are their metabolism (also known as secretions) and heredity.

Organisms have anabolism and catabolism, which are two opposite processes, and can reproduce, which is the basis of the phenomenon of life. The natural world is composed of living and non-living matter and energy, and inanimate (including matter and energy) are called non-living things, (metabolism is the most essential difference between living and non-living things).

A living thing is a living entity with kinetic energy and is also a collection of objects. With the exception of viruses, all living things are made up of cells. Viruses do not have a cellular structure and need to rely on host cells to reproduce, so life needs cells to behave, and viruses are no exception.

1) Except for a few species such as viruses, living organisms are made up of cells;

2) organisms have metabolic effects;

3) Organisms have growth phenomena;

4) Organisms are stressful;

5) Organisms can reproduce and develop;

6) organisms have both genetic and mutated properties;

7) Organisms can adapt to a certain environment and can also affect the environment;

8) Organisms are required to take in nutrients from the outside world.

9) Organisms are malleable.

10) Organisms are able to breathe.

All of the above basic characteristics are possessed only by living organisms, and cannot be possessed by non-living organisms. Therefore, these basic characteristics are important markers for judging and distinguishing living things from non-living things.

Cells are so small that they can only be seen under a microscope and come in a variety of shapes. It is mainly composed of the nucleus and cytoplasm, and has a cell membrane on the surface. Higher plants have a cell wall outside the cell membrane, plastids in the cytoplasm, chloroplasts and vacuoles in the body, and mitochondria.

Animal cells do not have a cell wall, and centrosomes are often present in the cytoplasm, while higher plant cells do not. Cells have functions such as locomotion, nutrition, and reproduction.

Organisms include protists, and organisms are a general term for individuals with life. Protists include unicellular eukaryotes, cell populations, and staged multicellular organisms.

1. The eight systems refer to:

Locomotor system. Nervous system.

Endocrine system.

Circulatory system. Respiratory system.

Digestive system. Urinary system.

Reproductive system. 2. Animals mainly include vertebrates and invertebrates. Vertebrates all have eight systems. Invertebrates don't have to be.

The sum of multiple organs in an organism that are composed to perform one or several physiological functions is called a system.

Here are a few special cases of invertebrates:

1.Protozoa is just one cell, so even if it can perform various functions, it cannot be called a system.

2.Ascaris do not have a locomotor system.

Animals have a digestive system, respiratory system, circulatory system, urinary system, endocrine system, nervous system, immune system, reproductive system, locomotor system.
