Prokaryotic and eukaryotic cells are the two main types of cells. Prokaryotic cells are simpler and lack a nucleus, while eukaryotic cells are more complex and have a nucleus.

Prokaryotic Cells

* Prokaryotic cells are the simplest type of cells.

* They lack a nucleus, mitochondria, and other membrane-bound organelles.

* Prokaryotic cells are found in all environments on Earth, including extreme environments such as hot springs and deep sea hydrothermal vents.

* Some examples of prokaryotic cells include bacteria and archaea.

Eukaryotic Cells

* Eukaryotic cells are more complex than prokaryotic cells.

* They have a nucleus, mitochondria, and other membrane-bound organelles.

* Eukaryotic cells are found in all multicellular organisms, as well as in some unicellular organisms.

* Some examples of eukaryotic cells include animal cells, plant cells, and fungal cells.

Table comparing prokaryotic and eukaryotic cells

| Feature | Prokaryotic Cells | Eukaryotic Cells |

|---|---|---|

| Size | Typically 1-10 micrometers | Typically 10-100 micrometers |

| Nucleus | No nucleus | Has a nucleus |

| Mitochondria | No mitochondria | Has mitochondria |

| Other membrane-bound organelles | No other membrane-bound organelles | Has other membrane-bound organelles, such as the endoplasmic reticulum and Golgi apparatus |

| DNA | Circular DNA | Linear DNA |

| Ribosomes | 70S ribosomes | 80S ribosomes |

| Cell division | Binary fission | Mitosis or meiosis |

| Habitat | Found in all environments on Earth | Found in all multicellular organisms, as well as in some unicellular organisms |
