High school biology to remember about bacteria and their role

1. Common bacteria: Escherichia coli (often used for cultivation experiments), staphylococcus, Vibrio cholerae, spirochetes, acetic acid bacteria (aerobic respiration to produce acetic acid), lactic acid bacteria (anaerobic respiration, kimchi, yogurt, etc.) These are prokaryotes to distinguish from fungi and molds.

2 Photosynthetic bacteria, nitrifying bacteria, the former can carry out photosynthesis, the latter can carry out nitrification, they are all autotrophs (general bacteria are heterotrophic).

3. Nitrogen-fixing bacteria (rhizobia and round brown nitrogen-fixing bacteria) can carry out nitrogen fixation and play an important role in the nitrogen cycle.

The front side is prokaryotic, and the back side is eukaryotic cyanobacteria, bacteria, radioactive bacteria, lactic acid bacteria, mycoplasma army, fungi, yeasts, molds.

Autotrophic type. Chemoautotrophics: nitrifying bacteria, sulfur bacteria, iron bacteria.

Photoautotrophics: photosynthetic bacteria.

Anaerobic: lactic acid bacteria, tetanus bacilli, denitrifying bacteria.

Aerobic type: round brown nitrogen-fixing bacteria, rhizobia.

Nitrogen-fixing bacteria: round-brown nitrogen-fixing bacteria, rhizobia.

Facultative anaerobic type: Escherichia coli.

nitrifying bacteria, nitrification in the n-cycle; rhizobia (symbiotic), round brown nitrogen-fixing bacteria (autogenous), nitrogen fixation in the n-cycle; Light and bacteria, light and action; If you are a Beijing candidate, these are basically enough. If not, forget it.

Some of the heterotrophic bacteria are saprophytic (i.e., live on dead organisms) and they are decomposers.

Bacteria that live parasitic (that is, live on living organisms) are also heterotrophic bacteria, but parasitic bacteria are not decomposers, and by definition, they should belong to consumers, but in high school organisms, organisms in this state of "parasitism" are generally not considered. For example, high school organisms view plants as producers, do not emphasize "autotrophs", and do not mention that plants also have parasitism (e.g., mistletoe) and predation (e.g., Nepenthes).

Heterotrophic bacteria are generally decomposers, because people say "average", so there is no need to consider special cases... Moreover, it seems that most heterotrophic bacteria are decomposers, otherwise, how can heterotrophic?

Parasitism with cellular bacteria, should be a symbiotic relationship with consumers? It seems uncertain, are mitochondria the consumers of people? I guess not.,The two concepts are kneaded together.。。。

Today's education is really rubbish, playing with these useless concepts every day, and those who write textbooks and exam questions over there don't hurt.

Saprophytic bacteria are decomposers, you add a general, it should be right, parasitic bacteria are naturally consumer heterotrophic.

Personally, I feel that it is more important to remember their names, common bacteria: **cocci, **spirochetes, **bacilli (lactic acid bacteria), etc.

Bacteria are prokaryotes and fungi are eukaryotes. One is simple and has no real nucleus, and the other has a real nucleus.

Most of the bacteria are called bacteria, only a few are fungi, find your own information to see what ** bacteria are fungi, remember, the remaining strange *** bacteria are prokaryotes...

To make a supplement, viruses should be divided into DNA viruses and RNA viruses.

Metabolic types and affiliations of common microorganisms: yeast: eukaryotic, heterotrophic facultative anaerobic, lactic acid bacteria:

Prokaryotic, heterotrophic anaerobic, can survive in acidic environments, nitrifying bacteria: prokaryotic, autotrophic aerobic, Escherichia coli: prokaryotic, heterotrophic facultative anaerobic, round brown nitrogen-fixing bacteria:

Prokaryotes, heterotrophic aerobic autogenous nitrogen-fixing type, Staphylococcus aureus: prokaryotic, heterotrophic facultative anaerobic type.

Bacteria (prokaryotes): shaped, such as bacilli, cocci, spirochetes, vibrio, etc., such as lactobacillus, acetobacter, Staphylococcus aureus, etc.

Actinomycetes (prokaryotes): do not belong to bacteria.

Fungi (eukaryotes): yeasts, molds (Penicillium, Aspergillus).

Cyanobacteria (prokaryotes): Generally refers to a class that can carry out photosynthesis, mainly cyanobacteria, trembling algae, hair cabbage, etc.

High school talks about probably these.

High School Biology Elective 1 Acetic Acid Bacteria.

The cell membrane can prevent germs and viruses from invading the cell, so that "some viruses and germs can invade the cell and make the organism sick", indicating that the cell membrane is relative
