in the nucleoid
in prokaryotes what does the cytoplasm contain?
ribosomes

cytoplasm or at plasma membrane
what are prokaryotes cell walls made out of?
peptidoglycan
what does the cell wall do in prokaryotes?(3)
- mainstains shape
- withstands hypotonic environment
- supports the cell
do eukaryotes have a simple or complex cell structure?
complex
how is DNA organised in eukaryotes?
into linear chromosones
which cell has small cells and larger cells?
small cells: prokaryotic
larger cells: eukaryotic
which cell is always unicellular and which cell is often multicellular?
unicellular: prokaryotic
multicellular: eukaryotic
which cell has a nucleus and membrane-bound organelles and which one hasnt?
nucleus+membrane-bound organelles = eukaryotes, prokaryotes do not have them
which cell has linear and which cell has circular DNA
linear= eukaryotic
circular= prokaryotic
which cell has small ribsomes which one has large
small=prokaryotic
large= eukaryotic
