| 1. | Lysosome |
| 2. | Smooth Endoplasmic Reticulum (SER) |
| 3. | Rough Endoplasmic Reticulum (RER) |
| 4. | Golgi apparatus |
| 1. | SER are the sites for lipid synthesis |
| 2. | RER has ribosomes attached to ER |
| 3. | SER is devoid or ribosomes |
| 4. | In prokaryotes only RER are present |
| (i) | The majority of energy production by animal cells occurs in the mitochondria. |
| (ii) | The cell wall protects the animal cell membrane from outside pressure differences. |
| (iii) | The endoplasmic reticulum plays a role in protein synthesis. |
