Has anyone taken a microbe test yet? We took one yesterday and thought it was an alright test. Questions on principles of microscopes and light, a few questions on diseases, using a microscope, identifying bacteria structure, it was stations that touched on a little bit of everything. Just wanted to check to see what others have been seeing on tests.

ON NO. I FORGOT TO STUDY THE MICROSCOPES.

Well, parts and functions of a cell are generally uniform among plant or animal cells. You just need to know why they're there so that you can answer questions asking what would happen if you took away one organelle, etc.
Microbial ancestry, I think, would only apply to mitochondria and chloroplasts - check in previous pages of the thread to learn about that.
It's not terribly hard, but if you don't want to memorize it I would suggest making a cheat sheet and learning to read 3-point font (no lie - that's how mine ended up last year).
When I mean ancestry, I mean something like Archea and such. And gram staining positive and negative.

Oh, whoops. Yes, you would definitely need to know Archaea and such. Gram-staining isn't that hard to learn about, but you might want to look into how it actually works, beyond "oh it makes things pretty colors".

On one pop quiz I actually mixed up the characteristics of the positive and negative. O.o It's a sign that I should study harder.

Microbial origin for mitochondria and chloroplasts (assuming you're talking about what everyone else has been talking about):
AlphaTauri wrote:Basically the theory is that mitochondria and chloroplasts are descended from ancient prokaryotic cells that formed symbiotic relationships with early eukaryotic cells. Over time, the DNA from the nucleus of the eukaryotic cell "took over" most of the DNA in the mitochondria/chloroplasts. The DNA that these organelles have today are remnants of the early prokaryotic cells' DNA.

Does anyone have a copy of the Microbe Mission test from the Greenhill invitational on Dec. 11? Those that went... what did you think of the test?

How in-depth do we have to go about each microbe? My mother is a microbiologist and is making me catalog the hemolysis and catalase results of every bacteria on my note sheet, as well as knowing about all the different types of staining, not just gram staining. Is this too much?

How do you guys find these articles on microbes? O.o

Ummmm, lets say...... that it's good for you, and she knows best? *looks up and studies*

It is always best to go above and beyond - you never know what a test might ask. Heck, just knowing a random fact about Chem was helpful for Fossils last year.
