- Animal Eukaryotic Cell Components: Structure And Function
I posted a picture of the eukaryotic animal cell earlier, but it was simply a labeled diagram. Here we will go into each of the major parts of the cell, as well as each organelle's function, not to mention the overall structure of the cell. As the...

Comparison between prokaryotic cell and eukaryotic cell
| Prokaryotic cell | Eukaryotic cell |
| 1. Lack of organized nucleus. Genetic material is present in the form of nucleiod | Well organized nucleus |
| 2. Nuclear membrane absent | Present |
| 3. DNA is not complexed with histones | DNA is complexed with histones to constitute chromatin |
| 4. DNA in a circular form and not packed into chromosomes | Linear DNA packed into well defined chromosomes |
| 5. Membrane-bound organelles are absent | Membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, Lysosomes, chloroplasts etc are present |
| 6. Cellular respiration is carried out by plasma membrane. | Cellular respiration by mitochondria. |
| 7. Absence of nucleoli and mitotic apparatus | Presence of nucleoli and mitotic apparatus |
| 8. Cell wall made up of murein | Cell wall present in plant cell is made of cellulose, hemicelluloses and lignin |
| 9. The cell membrane may infold to form mesosomes | Cell membrane does not from mesosome |
| 10. Flagella simple, made up of flagellin and 9+2 organization is absent | Flagella specialized and show 9+2 organization |
| 11. Cytoplasm does not show streaming movement | Cytoplasm usually show streaming movement |
| 12. Microtubules are absent | Microtubules present |
| 13. Ribosomes are of 70 S type | Ribosomes are of 80 S type. 70 S type of ribosomes, however occur in plastids and mitochondria |
| 14. Different kinds of pili present | Absent |
| 15. Replication of DNA occurs continuously throughout cell cycle | Replication of DNA occurs during S-phase of cell cycle |
