Viruses are molecular reproduction codes that use a living cell's reproductive capacity to proliferate. They are quiet analogous to computer virus codes that use other software to replicate. One is made of molecules and works on more complex molecular structures, the other is made of data bits and works on more extensive data groups.
Once a virus is inside a cell it causes the cell to reproduce itself (the virus) until the cell becomes clogged and dies or the cell wall bursts. Either will release the virus into the bloodstream to invade other cells.
Scientists debate whether viruses are alive because they lack the characteristics of traditional living organisms, such as the ability to reproduce on their own. Viruses depend on host cells to replicate and lack cellular structures that define life. Some argue that viruses are on the edge of life, while others consider them more as biological entities.
Because they can not reproduce on their own.
Scientists who do not consider viruses to be alive argue that they lack the ability to replicate on their own and do not perform essential metabolic processes without a host cell. While they can evolve and adapt like living organisms, they depend entirely on host cells for survival and reproduction. This leads some scientists to view viruses as complex biological particles rather than living organisms.
Some people argue that viruses are not alive because they lack any form of energy, carbon metabolism, and they canâ??t replicate or evolve. Therefore, they do not exhibit the same set of characteristics of all living things.
Robert Hooke did not include viruses in his observations because viruses were not discovered until the late 19th century when advancements in microscopy allowed scientists to see them. Hooke's work in the 17th century focused mainly on plant cells and microscopic structures in living organisms.

Most scientists consider viruses as the link between living an non living organisms. Viruses are considered non-living by some scientists because - 1) They donot perform any metabolic activities. 2) Outside the host cell , viruses are present only in crystalised form. (Even after it is un-crystalised , it does not lose it's capacity for infection) 3) It does not require any sort of "food".
Because they can not reproduce on their own.
Biologists don't use binomial nomenclature to name viruses because binomial nomenclature is reserved for living things. Viruses are not considers alive.
They don't, for the most part, that is. Scientists argue over whether or not viruses are alive because some believe that they have all the qualities you need to be considered alive, which are.... * They reproduce * They obtain and use energy * They grow and develop * They respond to the environment The only thing that is different is that they cannot use their genetic material on their own. They need a host, a cell, to reproduce. So therefore, scientists continue to argue on whether viruses are alive, or not. :D
Certainly not. It is a hotly debated subject. Viruses (and prions for that matter) are not alive in a conventional sense.
bacteria is but for viruses some scientists believe they are alive and others think they dont so i can't give you an answer to that

No, because viruses aren't alive.
No. Viruses are not cells. They invade cells to get the materials to copy their DNA. Many people do not consider viruses to be truly alive.
Need a host.
