The Problem of the Six Realms of Biological Systems Drop Masters please

You can see the details of the Six Realms system here.

Because different people have different demarcation methods, there is no complete conclusion, and the Six Realms system is the more mainstream demarcation.

A virus is not a cell and does not have the characteristics of life, but it is also considered by most people to be a living organism, at least a special organism.

A virus is a non-cellular life form, it is composed of a long nucleic acid chain and a protein coat, and the virus has no metabolic mechanism of its own, no enzyme system. As a result, when the virus leaves the host cell, it becomes a chemical substance that has no life activity and cannot reproduce on its own. Once in the host cell, it can use the matter and energy in the cell, as well as the ability to replicate, transcribe, and translate, to produce a new generation of viruses like it based on the genetic information contained in its own nucleic acids.

Viral genes, like genes in other organisms, can also be mutated and recombined, so they can also evolve. Because viruses do not have independent metabolic mechanisms and cannot reproduce independently, they are considered to be an incomplete life form. In recent years, a virus-like body that is simpler than a virus has been discovered, which is a small RNA molecule that does not have a protein shell, but it can cause disease in animals.

The existence of these incomplete life forms shows that there is no insurmountable gulf between inanimate and animate.

The six kingdoms of biological systems are Prokaryotic Kingdom, Fungal Kingdom, Protist Kingdom, Animal Kingdom, Plant Kingdom, and Virion Kingdom.

Viruses are organisms with a non-cellular structure, much smaller than cells, and can survive and replicate inside the host cell. The general composition of viruses is protein shell and genetic material DNA. Once in the host cell, it uses the material inside the host cell to replicate itself and then attack the good cell.

Viruses are living beings, of course! (All hand-to-hand, I'm an elective biology).

The six kingdoms of living things are the kingdom of plants, animals, fungi, viruses, protists, and prokaryotes Viruses are living organisms In the basic characteristics of living things, although viruses do not have a cell structure, they can reproduce, so they are considered to be living things.

The classification of several realms is based on the increase of people's knowledge level and understanding of the outside world, and thus the use of different standards.

Organisms are divided into phylums, families, genera (subspecies).

And the protists you are talking about belong to the phylum Protozoa.

The Six Realms System Solution.

Protists: Protozoa, unicellular algae, slime molds.

Prokaryotic kingdom: Bacteria (eubacteria and archaea), actinomycetes, cyanobacteria, mycoplasma, rickettsia, chlamydia.

Fungi: yeasts, molds, mushrooms.

Plantae: Animalia:

Viruses: Viruses, subviruses (viroids, viroids, prions) PS: Upstairs, viruses have cellular structures?

Here's our courseware: Virus Noncellular Organism (Euvirus): Subvirus (subvirus) containing at least two components: nucleic acid and protein

Viral-like: Contains only RNA components that are individually infective.

Viral: Contains only RNA components that are not individually infective.

Prions: Contains only one component of protein.

Since the 70s, Chinese scholar Chen Shixiang (1977) and some foreign scholars have proposed a perfect system of two general realms (six realms).

The two general boundaries are: the prokaryotic general boundary and the eukaryotic general boundary

The six kingdoms include: Virology, Schizon, Cyanobacteria, Fungi, Plants, and Animals.

Viruses belong to prokaryotes. If classified, organisms should be divided into two types: eukaryotic and prokaryotic.

Organisms refer to: animal biologically, plantly, protistically, prokaryotes, and microbial biologically.

Yes, this refers to living beings (i.e., living beings).

And that's not all.

Exactly, it's not an alien creature we haven't discovered!

Variants, classes. Subspecies: A small population of the same species in the same area with differential and stable inheritance, which has modifiers such as economic value and subspecies.

Subspecies are often found below the species. Variants: artificially selected populations and species.

2) A species has a certain genotype and phenotype. When further subdivided. Variety.

3) The species is stable and characteristic for a certain period of time. Species are taxonomically the smallest units, clawwed rice, general order: individual mutants, genera produced within the species, such as the general order.

Variants, families, stems, phylums. For example, rice is divided into indica rice, and the differences and variants caused by different environments: the distribution of the same species in different regions

1) Different species are reproductively isolated, and the concepts of suborders, orders, and varieties are developed in the long run, which is conducive to maintaining the stability of species, subclasses, etc., and can be added before the taxonomic level.

According to the evolutionary level of microorganisms and the obvious differences in various traits, they can be divided into three major groups: prokaryotes (including eubacteria and archaea), eukaryotic microorganisms (fungi, slime molds, and pseudobacteria in the fungal kingdom, starved microalgae in the plant kingdom and protozoa in the animal kingdom), and non-cellular microorganisms (euviruses and subviruses (viroids, pseudo-rotten and virulents, and prions)).

The classification system was proposed by biologist Trauba in 1975.

That is, the protists, fungi, plants, animals, archaea, and eubacteria.

The main taxonomic levels of organisms are phylum, class, order, family, genus, and species. There is also a subspecies (abbreviated as subsp.).There are also variety, abbreviated as var

Sometimes there are some auxiliary grades, which are really prefixed with super-and sub-Under subclasses and suborders, subclasses and suborders are sometimes set up separately.

circles"It is the first level of classification, and the classification method is not unified at present. For example, there are two kingdom systems: the animal kingdom and the plant kingdom.

Three realms system: animal kingdom, plant kingdom, protist kingdom.

Four Realms System: Prokaryotic Kingdom, Protist Kingdom, Plant Kingdom, Animal Kingdom Five Realms System: Prokaryotic Kingdom, Protist Kingdom, Fungal Kingdom, Plant Kingdom, Animal Kingdom Six Realms System:

The prokaryotic kingdom, the protist kingdom, the fungal kingdom, the plant kingdom, the animal kingdom, the virus kingdom and the recent three sources and six kingdoms are also said.

As for all the doors, the classification is even more varied. The minimum score is 20 and the maximum is 36. Forgive me for not writing them down one by one (it doesn't make much sense).

Finally give you a **.

You can take a look. It is classified according to the system of the six realms, and it is divided into genera. I think it's very concrete.

BTW, jellyfish belong to the animal kingdom, coelenterates (also called cnidarians), hydra or bowl jellyfish (you have to tell me which jellyfish I know below).

The prokaryotic kingdom, the protist kingdom, and the virion kingdom belong to microorganisms.
