I need a microscope power to see bacteria grown in petri dishes ...do you need a special microscope, or will a regular one do?

Viewing bacteria is at the limit of resolution for most light microscopes. Typically 1000x using an oil-immersion lens is required, and is the standard in microbiology labs.

They wouldn't be seen on a dissection scope. The difference in the two is basically magnification. Dissecting scope is more of a high powered magnifying glass. its gets about 4x magnification. Where a compound has much higher magnification 10 to 100x times. Stained bacteria could probably be seen under a dissecting but you would need a compound to differentiated between cocci or staph bacteria.

A regular light microscope will work fine, obviously the higher the magnification, the bigger the bacteria will show up. I would say try 400x. at least.

100x zoom usually allows you to see it. You need a higher powered microscope, which is usually standard anyway. I know that you'll be able to make out bacteria and what not with 100x zoom.

you would need a light microscope which is the most common microscope used in experiments such as yours.
