The cytoskeleton is made up of:
| 1. | calcium carbonate granules |
| 2. | callose deposits |
| 3. | cellulosic microfibrils |
| 4. | proteinaceous filaments |
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
| 1. | Intracellular transport |
| 2. | Maintenance of cell shape and structure |
| 3. | Support of the organelle |
| 4. | Cell motility |
| 1. | Transportation | 2. | Nuclear division |
| 3. | Protein synthesis | 4. | Motility |
| 1. | spindle fibres, centrioles and cilia |
| 2. | centrioles, spindle fibres and chromatin |
| 3. | centrosome, nucleosome and centrioles |
| 4. | cilia, flagella and peroxisomes |
