what are eukaryotes and prokaryotes?
- Prokaryotes are cells or organisms which do not have definite nucleus and membrane bound organelles. Example: Bacteria and Blue green algae.
- Eukaryotes are cells or organisms which consist of well defined nucleus and membrane bound organelles. Example: Animals and Plants.
Differences:
Prokaryotes | Eukaryotes |
Size of the cell is generally small (1-10 micro metre). | Size of the cell is generally large (5-100 micro metre). |
Nucleus is absent.
| Nucleus is present. |
It contains single chromosome.
| It contains more than one chromosome. |
Nucleolus is absent | Nucleolus is present |
Membrane bound cell organelles are absent.
| Cell organelles such as mito chondria,plastids,endoplasmic recticulam,golgi apparatus etc. are present. |
Cell division takes place by fission or budding (no mitosis) | Cell division occurs by mitotic or meiotic division. |
