Eukaryotic and Prokaryotic

Postby luvinpurple » Mon Sep 10, 2012 5:43 am

For an assignment I have to explain what the differences between eukaryotic animal, eukaryotic plant and prokaryotic cells are in detail and with examples. I could figure out the prokaryotic cell but not the differences between the eukaryotic plant and animal cells. If anyone knows anything about them could you please help me? Thanks :)

How about you start with cell wall, chloroplast...

If it's not too late already for your assignment, very briefly:
prokaryotic cells are in general much smaller than eukaryotic ones, they have no membrane-bound organelles, and the only organelles they have are ribosomes (which are also smaller than the ones in eukaryotes).
Prokaryotes are generally known as bacteria. Today they are grouped into two separate large "fields" or domains, the (true) bacteria and the Archaea or archaea bacteria.
The genetic material in prokaryotes is one single, ring-shaped chromosome, while in eukaryotes it is in the form of rod-shaped chromosomes.
Most bacteria have cell wall made in majority by peptidogylcans.
Eukaryotic organisms are divided into 4 kingdoms: the Protista (unicellular, both auto- and heterotrophic organisms; also multicellular algae are grouped in here), the plants, the fungi or mushrooms and the animals (including humans as well).
Plant and algal cells have cell walls which contain cellulose, while fungal cell have cell walls with chitin. Animal cells have never any kind of cell wall.
Major difference between most plant and animal cells are not only the presence/absence of cell walls, but in plant cells we find some organelles not present in animal cells, such as a large central vacuole, different plastids (of which the green chloroplasts, which are performing photosysnthesis are best known) and lack of centrioles.
