What three ways are viruses different from cells?

Answer 1

Viruses are acellular; they are not composed of a cell, and therefore are not alive. Bacteria are composed of a single cell and therefore are considered living.

Viruses are very much smaller around 10x than the average bacteria and are composed of little more than DNA or RNA (retro-viruses ex HIV) and a protective cover. Bacteria are prokaryotes meaning they have no membrane bound cellular organs but are more complex in structure than the virus.

Viruses replicate by invasion of a host cell integrating it's DNA/RNA into the host and having the host translate protein products to create new viruses which rupture through the cell wall of the host often stealing a membrane from the host in the process. This means all viruses must reproduce on/in something alive(biotic).

Bacteria reproduce by cell division. Bacteria do not have to have biotics to reproduce, they can reproduce in any suitable environment where growth is not limited.
I know that they are different because viruses are 10,000 times smaller than bacteria, antiboitics cannot kill viruses like they kill bacteria, and viruses need a living host to reproduce when bacteria produces on its own by binary fission.

Answer 2

• A virus does not have any organelle that is found in animal or plant cell
• Virus is surrounded by capsid, a protein shell, rather than cell membrane and cell wall.
• A virus is much smaller than an animal or a plant cell. It is even much smaller than a bacterial cell.
• Virus is not considered to be a cell, nor is it composed of cells.
• Rather than a nucleus, the nucleic acid of virus is housed in a protein shell, called capsid.
• Virus can only divide once inside a host cell, where it assembles clones of itself.
• Unlike animal or plants, viruses are not classified via binomial nomenclature.

Answer 3

Plant cells are stiff because their cell walls are rectangular.

They only have one vacuole, water sack, and have the ability to photosynthesize.

Animal cells are soft and round with many small vacuoles.

Those are THE MOST BASIC differences.

Answer 4

Viruses are nonliving and cannot make their own food, and do not use their own energy to grow.

Answer 5

Viruses are non~living, plants are. Viruses do not make their own food, plants do. Viruses don't use their own energy to grow, plants, once again, do.

Answer 6

they do not have cytoplasm, they take it from host cell

they do not have a cel membrane

they do not have a nuclear membrane
