What are the differences and comparisons between viruses and bacteria?

Posted on February 18, 2010 by admin

I have to do this PowerPoint for my biology class, and we have to compare and contrast viruses and bacteria.
But specifically these things:
Abiotic/Biotic
Structure of each
Reproduction of each
Diseases caused by each

So if you know these, it would be great.

Any other key information.

There are a number of differences between a virus and bacteria, or more appropriately, viruses and bacteria, including their relative sizes, reproduction methods and resistance to medical intervention. Bacterium, the singular form of the word bacteria, is a one-celled living organism, with complete sets of both ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) genetic codes. A virus is little more than a section of RNA or DNA covered by a protein shell. Bacterium, therefore, is at least a hundred times larger than a typical virus.

    First of all, realize that a virus is not considered a living creature and a bacteria is.

    Next I ll try to answer your question.

    I can’t explain it better then wikipedia does so..
    http://en.wikipedia.org/wiki/Bacteria#Metabolism

    Over here you ll just find everything you need to know about bacteria ;)

    Virusses dont feed as far as I know, they just use the protein building machinery from their host cells to make their new parts ;) they come in 4 structures and can reproduces via 2 mechanisms the lysogenic and lytogenic cycle

    Here you can read some more about it.. It could type about 3 pages about this subject, its very big but it would be better to use this post as some guide to find your info on the web ;) Good luck
