Structure of a Prokaryotic Cell
- General size is approximately 1-2 um
- Lacks any membrane-bound organelles
- The Ribosomes are smaller than that of a Eukaryotic Cell
- Flagellate bacteria have the flagellum
- It has naked DNA (not membrane-bound)
- The DNA is a continuous circle
Functions of Prokaryotic Organelles
Cell Wall- Made of murein (not cellulose) in a protein/carbohydrate complex (peptidoglycan).
Plasma Membrane- Controls the entry and exit of substances, pumping some of them by active transport.
Ribosome- Smaller, and found free in the cytoplasm, not attached to a membrane (RoughER). Used in protein synthesis (gene expression).
Nucleoid- The region in the cytoplasm that contains the DNA, it…
