Prokaryotes and Eukaryotes

Postby TheVirus » Sun Jun 19, 2011 5:27 pm

Hey, I'm doing some work for my first year of university. I've been asked to explain all the differences between these two cell types. I've already mentioned the main differences, but i'd like your input to make sure I cover everything.
Thanks

what if you've showed your input first and we can comment it

Cis or trans? That's what matters.

All righty.
Prokaryotes:
-DNA stored in nucleoid
-No membrane-bound organelles
-Smaller ribosomes
-Higher growth and metabolic rate
-Less life time per generation

Eucariotes:
- Nuclei present, DNA stored in chromosomes
-Membrane-bound organelles present
-Bigger in size

I guess this would be enough but it wouldn't hurt to have some extra data.
Thanks

what about metabolism? Cellular defense?

I can't find anything on cellular defence for prokaryotes and eukaryotes. Could you give a link or something? I can't find anything that specific.

P:
-cell division: asexual reproduction, usually by binary fission
-plasmalemma: rigid, very selective
-nucleoid is a circular chromosome (DNA) without nuclear envelope
-http://en.wikipedia.org/wiki/Prokaryote


E:
-cell division: indirect: mitosis and meiosis
-plasmalemma:flexible, high permeability
-true nucleus with envelope
-http://en.wikipedia.org/wiki/Eukaryote

Maybe u can also include 70s or 80s ribosomes, present of absent of plastids, mitochrondria, chloroplast...
