Cells:
The structure of eukaryotic cells:
Cell surface membrane
Nucleus (containing chromosomes, consisting of protein bound,
linear DNA and one or more nucleoli)
Mitochondria
Chloroplasts (in plants and algae)
Golgi apparatus and golgi vesicle
Lysosomes (membrane bound organelle that releases hydrolytic
enzymes)
Ribosomes
Rough endoplasmic reticulum and smooth endoplasmic reticulum
Cell wall (in plants, algae and fungi)
Cell vacuole (in plants)
The structure of prokaryotic cells:
Prokaryotic cells are much smaller than eukaryotic cells. They
also differ from eukaryotic cells in having:
Cytoplasm that lacks membrane bound organelles
Smaller ribosomes
No nucleus instead they have a single circular DNA molecule that
is free in the cytoplasm and is not associated with proteins.
A cell wall that contains murein, a glycoprotein.
One or more plasmids
