The solid linear cytoskeletal elements having a diameter of 6 nm and made up of a single type of monomer are known as:
1. Microtubules
2. Microfilaments
3. Intermediate filaments
4. Lamins
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
