Is a virus bigger than a cell?

Answer 1

A virus is much larger than bacteria. Generally, bacteria are several orders of magnitude larger than viruses.

Most bacteria are measured in micrometers (or millionths of a meter). Most measure between 1 and 5 micrometers.

Viruses are measured, on the other hand, in nanometers, or 1000th a micrometer. The virus causing the common cold, the rhinovirus, is about 20 nanometers.

Answer 2

A virus is of course non-cellular. Its typical size is 20-30nm. They contain no cytoplasm or organelles and no chromosomes just RNA and DNA strands. They are covered in a protein coat. They cannot function out side of a living cell, they need a host cell to use its organelles to reproduce and function. But as you know a normal cell is a complete opposite, they can function and reproduce on their own due to their nucleus and they do contain cytoplasm,organelles and chromosomes as well as RNA and DNA strands.

Answer 3

Quite a bit.
With a diameter of 220 nanometers, the measles virus is about 8 times smaller than E.coli bacteria. At 45 nm, the hepatitis virus is about 40 times smaller than E.coli.
For a sense of how small this is, David R. Wessner, a professor of Biology at Davidson College, provides an analogy in a 2010 article published in the journal Nature Education: The polio virus, 30 nm across, is about 10,000 times smaller than a grain of salt.
Such differences in size between viruses and bacteria provided the critical first clue of the former’s existence.

Answer 4

No.

Virus particles are slightly smaller than a cell.

Answer 5

Viruses are much much smaller than bacteria, roughly near two orders of magnitude smaller (although there is considerable variation between species of virus as to actual size).
