How do viruses differ from bacteria fungi and parasites?

Answer 1

Viruses aren't as "living" as the other three that you mentioned. The only thing viruses have in common with them is that they move. Viruses do not eat, breath, grow, or reproduce. They do reproduce, but not independently.

Instead of taking over the host right away, many viruses go into a dormant stage, which means that they wait for the right time and climate (which could even take over a year, like most symptoms of HIV, for example) to do their job. Also, viruses do not attack until inside the cell wall. From there, the virus sends genetic material into the cell membrane, and the cell immediately goes to work reproducing the virus.

The only reason viruses care to survive is to reproduce, and we don't know why.

The first paragraph should have mainly answered your question, I just wanted to make sure you know the important facts--they help. Please give feedback! Thanks.

Answer 2

Covered by--

Virus is covered by protein coat

Bacteria is covered by cell wall

Fungi is covered by a cell wall

Cell Membrane--

Virus-No

Bacteria-Yes

Fungi-Yes

Cytoplasm--

Virus-No

Bacteria-Yes

Fungi-Yes

Genetic Material--

Virus has DNA or RNA; only a few genes present

Bacteria has DNA and RNA both' enough for several hundres genes

Fungi is a Eukaryotic carrying definite nucleus with enough genes

Living or Non-Living--

Virus- non-living outside host cell

Bacteria- living

Fungi- living

Size--

Virus- 30-300nanometer

Bacteria- 0.1-10micrometer

Fungi- macroscopic(exception yeast)

Useful or Harmful--

Virus- harmful(exception biological control)

Bacteria- useful in producing antibyotics

Fungi- useful

Parasatic or Sacrophytic--

Virus- parasatic or pathogenic

Bacteria- pathogen as well as sacrophytic

Fungi- some are parasatic; some are parasatic

Can Culture--

Virus can only culture in chicken eggs(cannot be grown in artificial medium)

Bacteria can culture in artificial medium

Fungi can be grown in artificial medium

In Crystallised Form--

Virus- You can keep them crystallised and they can grow again when introduced to a new host

Bacteria- cannot be kept im crystallised or kept in powder farm-they will die

Fungi- cannot be crystallised as they would die

Microscopic--

Virus- can be seen using an electron microscope

Bacteria- can be seen using compound microscope

Fungi- can be seen by using compound microscope
