PROKARYOTIC CELLS: This is how prokaryotes received their name: Pro= Before, Karyon=Nucleus
Summary: the structure of prokaryotic cells. Prokaryotic cells have a simple structure, meaning prokaryotes are always unicellular. Prokaryotic cells are cells that do not have a nucleus, but they do have a: · Cell membrane · Cell wall containing peptidoglycan · Cytoplasm · Circular DNA floating in the cytoplasm Some prokaryotes have additional small loops of DNA containing extra genes, known as plasmids floating in the cytoplasm. No membrane-bound organelles, such as mitochondria and chloroplasts, are found within the cytoplasm. Some prokaryotes have a flagellum or several flagella. Flagella are long thin whip-like projections (tails) used in cell movement. EUKARYOTIC CELLS: Most of the living things you see every day are made up of eukaryotic cells.

- These include mitochondria, chloroplasts, golgi bodies, endoplasmic reticulum and lysosomes. All these are found in eukaryotic cells, which are complex. - Prokaryotes are much simpler, reflecting their early evolution compared to eukaryotes.
