Answer 2

Verifying the Statements

Let's verify the statements one by one:

1. Вирусная частица состоит из одной клетки (The viral particle consists of a single cell). 2. Вирусы хорошо видны в световом микроскопе (Viruses are clearly visible under a light microscope). 3. Вирусы не имеют клеточного строения (Viruses do not have cellular structure). 4. Вирусы мельче бактерий (Viruses are smaller than bacteria). 5. Вирусы свободно размножаются вне живых организмов (Viruses freely reproduce outside living organisms).

Verifying Statement 1: Вирусная частица состоит из одной клетки (The viral particle consists of a single cell)

This statement is incorrect. Viruses are not considered cells. They are much simpler in structure compared to cells and are often described as particles rather than cells. Viruses consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses may also have an outer envelope derived from the host cell membrane. However, they lack the cellular machinery necessary for independent metabolism and reproduction.

Verifying Statement 2: Вирусы хорошо видны в световом микроскопе (Viruses are clearly visible under a light microscope)

This statement is incorrect. Viruses are generally too small to be seen under a light microscope. The size of viruses ranges from about 20 to 300 nanometers, which is much smaller than the resolution limit of a light microscope. To visualize viruses, electron microscopes are typically used, which have much higher magnification and resolution capabilities.

Verifying Statement 3: Вирусы не имеют клеточного строения (Viruses do not have cellular structure)

This statement is correct. Viruses do not have cellular structure. Unlike cells, they lack organelles, cytoplasm, and other cellular components. Viruses are considered acellular entities because they cannot carry out essential life processes on their own. They rely on host cells to replicate and reproduce.
