Which one of the following cellular parts is correctly described?
| 1. | Thylakoids-flattened membranous sacs forming the grana of chloroplasts |
| 2. | Centrioles - sites for active RNA synthesis |
| 3. | Ribosomes-those on chloroplasts are larger (80S) while those in the cytoplasm are smaller (70S) |
