An elaborate network of filamentous proteinaceous structures present in the cytoplasm which helps in the maintenance of cell shape is called:
1. Endoplasmic Reticulum
2. Plasmalemma
3. Cytoskeleton
4. Thylakoid
The cytoskeleton is made up of:
| 1. | calcium carbonate granules |
| 2. | callose deposits |
| 3. | cellulosic microfibrils |
| 4. | proteinaceous filaments |
