Microbe Mission B/C

Typo on training handout? : Eukaryotic cells are structurally and biochemically more complex than Eukaryotic cells
should it be Eukaryotic cells are structurally and biochemically more complex than prokaryotic cells

Ohhh. Thats really helpful. :D

arent the prokaryotes multi-celled organisms like us and eukaryotes are single celled, like bacteria?

[AlphaTauri]

Flipflop your definitions.

Prokaryotes are simpler cells that only have a cell membrane and maybe a cell wall, cytoplasm, ribosomes, and DNA floating around (they don't have nuclei). They are usually single-celled organisms like bacteria.

Eukaryotes are more complex cells that have nuclei and many different organelles. They are often part of larger organisms (plants, animals, fungi).

To clarify, eukaryotes are often, but not necessarily multi-cellular. Protozoa for example are single celled eukaryotes.

Question: Are Prokaryotic colonies (such as bacterial colonies) considered multi-cellular? I know that the individual bacteria are not, but if someone asked on a test, "Can prokaryotes be multi-cellular?", what would one say?

Bacterial colonies like Volvox are a popular topic of debate for scientists, as they have properties of uni and multicellular organisms, currently I believe scientist do NOT classify them as multicellular because a single bacteria can split off and live its own life or something like that. For the other question, I think (not sure on this) scientists believe that multi-cellular prokaryotes might exist but haven't been found yet or something.
My question: Does anyone have any tips for identifying microbes and/or what type of microscope was used from pictures?

My question: Does anyone have any tips for identifying microbes and/or what type of microscope was used from pictures?

What I've done is create flashcards of a bunch of each of the different types of microbes citing what it is and what microscope was used. Look for similarities between those take with similar microscopes- some you might find have grater color depth ( but be sure that they have not been enhanced)while others are very precise when it come to detail.

unfortunately i have not found a single source with many pictures of all of the microscopes under different scope, but i have found that universities and allied professional organizations are a good place to start.
I've been asking my self the same question-hope this helps!

does anyone have any good microbe sites? Our couch for this event is being a but and has only told us to google a couple of things and given us one lame website.
Thanks!! :D
