Viruses and Their Characteristics
Viruses are not classified as micro-organisms since they are acellular entities that lack cellular structure. They are smaller than micro-organisms like bacteria and fungi, making them the smallest infectious agents.
Characteristics of Viruses
- Viruses do not respire, feed, excrete, or move on their own. They lack the necessary cellular machinery and metabolic processes to carry out these functions. Instead, they rely on host cells to replicate and produce new viral particles.
- Viruses are obligate intracellular parasites, meaning they can only replicate inside host cells. They hijack the host cell's machinery to replicate their genetic material and produce new virus particles.
- Viruses can infect a wide range of hosts, including animals, plants, fungi, bacteria, and even other viruses. Each virus is specific to its host and often causes diseases in the infected organism.
Reproduction of Viruses
- Viruses cannot reproduce on their own; they require a host cell to replicate and produce new viral particles. In the case of bacteriophages, which infect bacteria cells, the virus injects its genetic material into the host cell and uses the cell's machinery to replicate and assemble new viruses.
- Once the new viral particles are formed, they can burst out of the host cell, destroying it in the process. This cycle of infection, replication, and release can lead to the spread of the virus to other cells and hosts.
In conclusion, the incorrect statement about viruses is that "Viruses can reproduce in bacteria cells." Viruses require host cells, such as bacteria cells or animal cells, to replicate and reproduce, as they lack the necessary cellular machinery to do so on their own.
