They also don't have a cytoskeleton. Their DNA is not seperated from the rest of the cell by membranes, they lack membrane-bound organelles. They have tough external cell walls. Cell division is accomplished by binary fission. Oh, and they are usually between .1 and 10 um in size(um is one millionth of a meter)
an organism that does not have a nucleus, hence has a naked loop of DNA....
is known as a prokaryote

it is a cell without a distinct nucleus, anything with a nucleus is a eukaryotic cell
Group of organisms that lack a cell nucleus (= karyon), or any other membrane-bound organelles. They differ from the eukaryotes, which have a cell nucleus. Most are unicellular, but a few prokaryotes such as myxobacteria are an exception.

prokaryotes are mainly bacteria. Metabolic activity: Some photosynthesise, some use nitrogen fixation and some use fermentation
mainly just bacteria...they dont have a nucleus and the genetic info just floats around in the cell. (chromosomes)
unicellular organisms are prokaryotes
I remember it from school lol
organisms whose genetic material is not contained within a nucleus
 Where was the last debate on wednesday with Mccain and Obama?
