What are the differences between bacteria and viruses GCSE?
Bacteria can produce toxins that make you feel ill. Viruses live and reproduce inside your cells, causing cell damage. Pathogens can be spread by direct contact, by air, or by water.
What is the differences between bacteria and viruses?
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
What are 3 differences between viruses and bacteria?
Viruses are tinier: the largest of them are smaller than the smallest bacteria. All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.
What is bacteria GCSE?
Bacteria are microscopic single-celled organisms. Examples of bacteria include: Lactobacillus bulgaricus (a rod-shaped bacterium used to make yoghurt from milk) Pneumococcus (a spherical bacterium that acts as the pathogen that causes pneumonia)
What is a virus GCSE?

What are the differences between a virus and a bacteria Class 9?

Bacteria can survive without a host but Viruses will die without a host. Bacteria reproduce through binary fission and Viruses reproduce through lytic fission.

What is the difference between virus and bacteria Class 8?
Of the many types of microbes, bacteria and virus cause a majority of the diseases….Difference Between Virus And Bacteria.
| Bacteria | Virus |
|---|---|
| Non-Living/Living | |
| They are living organisms | They can replicate only within the host cell |
| Mode of Reproduction | |
| Reproduce asexually by binary fission | Insert their genome in the host genome and make multiple copies |
How are viruses and bacteria similar?
Bacteria vs viruses Bacteria and viruses are too tiny to be seen by the naked eye, can cause similar symptoms and are often spread in the same way, but that’s where the similarities end. A bacterium is a single, but complex, cell. It can survive on its own, inside or outside the body.
