unfavorable conditions

Creation of conditions unfavorable to bacterial life is the basis of which process?

Processes 2, 3, and 4 take place in the presence of bacteria. In the presence of bacteria jam will go bad, so it is boiled with sugar.

Bacteria VS plants

What do bacteria have that plants do not?

A, B and D are the signs of plants. Bacteria unlike plants have circular DNA.

way of the power

By way of this power the vast majority of bacteria are

Most bacteria recycle dead organic matter to minerals, thereby the bacteria close the cycle of matter.

Bacteria 1

Bacteria that feed on organic matter of dead organisms are

Parasites are fed by ready-made organic compounds of living organisms. Symbionts live together, bringing benefit to each other. Chemotrophs produce organic matter from inorganic, using the energy of the disintegration of inorganic compounds. Saprotrophs feed on dead organisms.

Bacterial cell

Bacterial cells unlike animal cells have NO

Bacterial cells contain small organelles, and the mitochondria is not present. They are replaced by the invagination of the plasma membrane, and the energy process occurs in one stage (glycolysis).

Bacteria 2

What do bacteria have and fungi do not have?

A characteristic feature of bacteria is the presence of a circular DNA (nucleoid). The other signs are characteristics of fungi.

The ability

A common feature of all bacterial, plant, fungi and animal cells is the capability of

Living organisms are open systems engaged in a continuous exchange of matter and energy with the environment.

Difference 2

What is the difference between the prokaryotic and eukaryotic cells?

Prokaryotes are nuclear-free organisms. 
The rest of the answers show the similarities: hetorotrophs may be both prokaryotes and eukaryotes; sporulation is also a capability of both; the absence of the process of photosynthesis is common for all prokaryotes except cyanobacteria, animals and mushrooms that are eukaryotes.


Which of the following organelles do cells of bacteria have?

Membrane structure (organelles) is a characteristic of eukaryotic cells. There are none of them in bacteria.
Bacteria have ribosomes. Eukaryotic and prokaryotic ribosomes are similar in molecular structure and mechanisms, but differ in the size, composition of proteins and protein factors.

Hereditary unit

Which of the following has the hereditary unit that is located in the nuclear field?

Diphtheria bacillus is the bacteria that is a prokaryote and has the means of DNA in the cytoplasm (nucleoid).

Without bacteria

What is produced without the participation of bacteria or fungi?

Buckwheat is produced from plants that are called buckwheat.
Penicillin is obtained from strains of the fungi Penicillium.
Yeast dough is prepared by Fungi (yeast).
Cheese is a food product derived from milk using milk clotting enzymes and lactic acid bacteria or by melting various materials of dairy and non-dairy origin with salts-melters.


Which process do cyanobacteria, unlike saprotroph bacteria, carry out?

Cyanobacteria (blue-green algae) are a large group of large Gram-negative bacteria capable of photosynthesis, accompanied by the release of oxygen.
Saprotroph is a heterotrophic bacteria fed on ready-made organic matter of dead residues.

Certain species of bacteria

Certain species of bacteria are able to survive for a long time, as they

The formation of spores of bacteria is a factor of species saving in adverse conditions (changes in temperature, pH, lack of nutrients, the presence of toxins and so on.).


Some bacteria survive in the permafrost in which form?

Bacteria are transformed into spores under adverse conditions.

Difference 3

What is the difference between spores and free bacteria?

Spore of bacteria has a dense membrane, it is one bacterial cell, it is more durable than the bacteria and spores do not feed.

Reserve carbohydrates

Reserve carbohydrates of fungi constitute

Reserve carbohydrates of fungi constitute glycogen.


Chitin is a part of

Chitin is a part of yeast cell membranes.

an independent kingdom

Why do bacteria form an independent kingdom of organic life?

The bacteria are isolated as an independent kingdom of organic life because they are prokaryotes (cells that do not contain nuclei).


What fungus is grown specifically for drug production?

Penicillin antibiotic is produced by the penicillium.


The similarity of the vital processes in some bacteria and flowering plants is due to the capability of

Some bacteria are autotrophs: cyanobacteria and chemosynthetic bacteria; flowering plants are also autotrophs.


What are the activators of tuberculosis?

The causative agent of tuberculosis is the tubercle bacillus.

Bacterial spores

Bacterial spores unlike fungi spores

The spores of plants, fungi and sporozoa are used for breeding. Bacterial spores are used to adjust to adverse conditions.


Murein is the basis of which cell walls?

Murein is the basis of the cell wall of the bacteria - diphtheria bacilli.
