A bacterium is a microorganism that belongs neither to anything nor to something

A bacterium is a microorganism that belongs to neither plants nor animals.

Bacteria refer to one of the major groups of organisms and belong to the bacterial domain. It is also the most abundant group of all organisms, with an estimated total of about 5,10,30 individuals. The shapes of bacteria are quite varied, mainly globular, rod-shaped, and spiral-shaped.

Bacteria also have a great influence on human activities. On the one hand, bacteria are the causative agents of many diseases, which can be transmitted between normal human bodies through various ways, such as contact, digestive tract, respiratory tract, insect bites, etc., which are highly infectious and extremely harmful to society. On the other hand, bacteria are also often used by humans, such as the production of cheese, yogurt and wine, the manufacture of some antibiotics, and the treatment of wastewater.

In the field of biotechnology, bacteria are also widely used.

A bacterium is a microorganism that belongs to neither plants nor animals.

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. Microorganisms are all microscopic organisms that cannot be seen or seen clearly by the naked eye, and the organisms with tiny individuals and simple structures can usually be seen clearly with optical microscopes and electron microscopes, collectively referred to as microorganisms. Whereas, bacteria conform to the characteristics of microorganisms.

2. Microorganisms include bacteria, viruses, molds, yeasts, etc. (However, some microorganisms are visible to the naked eye, such as mushrooms, reishi, etc., which belong to fungi.) Viruses are a class of "non-cellular organisms" made up of a handful of components such as nucleic acids and proteins, but they must depend on living cells for their survival.

According to the different environments present, it is divided into prokaryotic microorganisms, space microorganisms, fungal microorganisms, yeast microorganisms, marine microorganisms, etc.

The characteristics that do not belong to microorganisms are: species list.

1. Weak adaptability;

The characteristics of microorganisms are: small individuals and simple structures; It is extremely widely distributed and diverse; Rapid reproduction and huge numbers; Diversification of metabolic types; It is easy to bridge the game to mutate;

Expansion: Microorganisms refer to a large group of organisms including bacteria, viruses, fungi, some small protists, microscopic algae, etc., which are small and closely related to humans.

It covers many types of beneficial and harmful, and is widely involved in food, medicine, industry and agriculture, environmental protection, sports and many other fields. Some microorganisms can be seen with the naked eye, such as mushrooms, ganoderma lucidum, shiitake mushrooms, etc., which belong to fungi. There are also microorganisms, which are a class of "non-cellular organisms" that are made up of a few components such as nucleic acids and proteins.

a.It is used in the preparation of antibiotics.

b.A large amount of O2 can be produced during life activities

c.Cause infective rock disturbances.

d.Provides vitamin K to humans

e.Caused contamination in the jujube laboratory.

The answer is b

Answer]: A fungus is a type of eukaryotic organism. The most common fungi are mushrooms, but fungi also include molds and yeasts.

Option A is a virus, and B, D, and E are prokaryotic microorganisms, all of which belong to the category of generalized bacteria, including bacteria, actinomycetes, mycoplasma, chlamydia, and stupid, rickettsia, and spirochetes.

a.Bacteria: Bacteria are a class of single-celled microorganisms that can be found in soil, water, air, or parasitic in other organisms. They have a cell wall and a cell membrane and can reproduce by merging and fissures.

b.Fungi: Fungi are a class of multicellular microorganisms that include many different species, such as yeasts and molds. They reproduce by means of spores, which can break down organic matter, and some fungi can also form mycelium.

c.Plasmodium: Plasmodium is a parasite that belongs to the phylum Protozoa and can infect humans and other animals. It is transmitted by mosquito bites and can parasitize red blood cells to cause malaria. Only model.

d.Chlamydia: Chlamydia are a class of bacteria-like microorganisms that are non-autotrophic intracellular parasites that require the host cell to provide nutrients.

Chlamydia have a different cell wall structure than bacteria, and they are not able to metabolize autonomously. Chlamydia infection often causes cold-like symptoms.
