Why is there is debate about the viruses being alive or dead?

The debate is not about whether viruses are alive or dead. Rather, there is debate about whether a virus should be considered a living thing. Viruses are not like living cells, because they do not have metabolic processes, and they cannot reproduce themselves. Instead, they invade a host cell, and the virus's genes cause the host cell to produce new viruses. However, the question of whether this "counts" as being alive is a semantic one. Viruses have some properties of living things, and they lack other properties, so the question of whether they are "alive" comes down to one's definition of the word "life."


Do viruses grow on dead cells?

Viruses that enter a cell do not die. A virus cannot reproduce on its own so it needs to find a cell in which to live. After the virus is done reproducing, most host cells die.


Do scientist consider viruses to be living?

What viruses do is they are not living, so they use the cell's life to 'reproduce'. They take all of the cell's nutrition and use that to multiply. Then the cell is dead, and the viruses go on to take over more cells.


Are viruses alive or dead?

Although they consist of the same types of DNA amd protein as living cells, viruses may be considered as different from living cells, for these reasons: -- they don't use energy to grow or reproduce -- they cannot reproduce on their own: they need a "host" cell that will turn their genetic material into more viruses -- they don't eat or produce waste. Viruses do not die as other organisms do, and can persist for very long periods in adverse conditions. The only ways to render them "dead" is to either remove their protein coatings, or to denature the molecules within them. This can sometimes be done by heat, and sometimes by using chemicals that nullify their genetic material's ability to reproduce. They cannot be starved or poisoned, as is done with bacteria.


Do viruses reproduce with live or dead?

viruses are nonliving things. but they need living things to reproduces. so live


Is mumps alive?

No: Mumps is a virus, and by definition viruses are nonliving, neither dead or alive.


Are cells of the stratum granulosum alive?

the superficial cells of stratum granulosum are dead,but the deeper cells are alive.


When do viruses reproduce?

viruses can not reproduce without the help of a living cell(host).they remain inert or dead(in-active) when they are in free environment or outside the body(host).when they enter the living cell or in some cases insert their nucleic acid into the host,it takes over the host's biosynthetic machinery and forces it to reproduce essential viral components and after proper assembly the cell burst and viruses leave the cell to infect other cells


How can viruses eat?

Viruses cannot eat because they lack the cellular machinery for metabolism. Instead, viruses hijack host cells and use their machinery to replicate themselves. This process often damages or destroys the host cell.


Can you have dead sperm cells?

If a cell can possibly be alive, then it certainly can be dead.


Are viruses devoid of any biochemical machinery and thus behave like dead particles inside the cell?

viruses behave like dead particles out of the cell and in specific out its particular cell. Once inside its cell, the virus uses the cell's machinery to "come alive" it then begins to reproduce and infect other of the same type of cell.


Why are viruses is considered to be non living?

They are not dead or alive, although there is an ongoing debate to whether viruses are alive or not.A virus (from the Latin virus meaning toxin or poison) is a microscopic infectious agent that can reproduce only inside a host cell. It is able to mutate, because of the difference in the DNA of the host. Your body can create antibodies of a virus or with a vaccination, a dormant virus can be inserted into your body, and your body will create antibodies of the dormant virus. Although, there is an ongoing debate to whether viruses are alive or not. With the facts given, it is up to you to decide if viruses are alive or not. All Living things:-are composed of cells with a complex, organized structure-actively maintain their complex structure and internal environment (homeostasis)-respond to stimuli in their environment-acquire and use materials and energy from their environment and convert them into new forms-reproduce, using the molecular blueprint of DNA-have the capacity to evolveViruses:-are not made of cells and do not have cells-cannot accomplish the basic tasks of living cells-have no ribosomes to make protein-have no cytoplasm-cannot acquire energy or steal the host's energy-cannot grow or reproduce by themselves or with other viruses-do not respond to stimuli-cannot maintain a stable internal environment-can evolve
