Differences between a Prokaryotic cell & Eukaryotic cell
Prokaryotic cell | Eukaryotic cell |
Absence of definite nucleus, nuclear membrane, nucleolus | A well defined nucleus bound by a nuclear membrane, and nucleolus is present |
Membrane bound organelles like Mitochondria, Endoplasmic Reticulum, Golgi Apparatus, Lysosome, Chloroplasts etc. are absent. | Presence of membrane bound organelles |
Cell respiration is carried out by the plasma membrane. | Cell respiration by mitochondria |
Has only a single prokaryotic chromosome (DNA), located in the cytoplasm. | Has many chromosomes enclosed within the nucleus |
DNA is usually circular. | DNA is linear |
Histones (basic proteins) are absent. Hence chromosomal DNA is not complexed with them. | Histones are present. So chromosomal DNA is complexed with histones |
Cytoplasmic streaming is absent. | Cytoplasmic streaming is present |
Cytoplasmic microtubules and microfilaments are absent. | Microtubules and microfilaments are present |
