Difference between Prokaryotes and Eukaryotes Fatima Nadeem AS Level Biology 9 May 2020 biology

Nucleus: No true nucleus . No membrane bound organelles (Nucleoid).

single chromosomes.

Flagellum if present simple,built from two proteins.

cell walls made of Peptidoglycan .

Small ribosomes.

Tough cell wall.

Circular DNA

E.g: Bacterial cell

Liner DNA in nucleus.

Size of Cell: 10 to 100 mm in diameter.

Nucleus: has distinct nucleus. Covered by nuclear envelope.

Several membrane bound organelles.

Several chromosomes

Chemically simple cell walls. cellulose : plant , Chitin: fungi.

Flagellum if present complex , built from microtubules.

May have cila.

Large DNA

E.g: Cells of multicellular organisms.like Plants and animals cell

Lacks cytoskeleton.

Prokaryotes: size 0.2 to 2.0 mm in diameter.

Prokaryotes

Eukaryotes
