Prokaryotes!

Post by NewtoBiology » Sat Feb 09, 2008 3:43 pm

Hello everyone,

If anyone could throw some ideas at me I would be so grateful!!!

I am studying prokaryotes and their nutritional diversity in comparison to eukaryotes. My question is WHY are prokaryotes so much more nutritionally diverse??

I can imagine it is due to:

a. single celled, simpler structure, smaller in size
b. Prokaryotes can be found anywhere


But is that really answering the questions?!?!? Or am I just rambling.

Any ideas or direction?

THANK YOU!!!

I mean that prokaryotes can be autotrophs, photoautrophs, chemoautotrophs, heterotrophs, whereas eukaryotes are not.

Huh really? If you consider plants, the only one that eukaryotes don't really do is chemoautotroph.

A broader question you should ask is why are bacteria so diverse? From that I think you can argue why they eat more things.

Fast generation time (e.g. 20 min for E.coli) allows fast evolution toward the gain of beneficial mutations in the new environment.
Ability to exchange plasmids/genes with other bacteria to acquire new phenotypes.
