Which one of the following is an elaborate network of filamentous structures present in the cytoplasm?
1 Cytoskeleton
2 Centrosome
3 Central microtubule
4 Inter-doublet bridge
Explanation:
An elaborate network of filamentous proteinaceous structures present in the cytoplasm are referred to as the cytoskeleton. It is involved in many functions such as mechanical support, motility, maintenance of the shape of the cell.

Assertion : Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements. Reason : Cytoskeleton is responsible for it.
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false
Explanation:
The cytoskeleton is a fibrous network made of proteins that contributes to the structure and internal organisation of eukaryotic cells within the cytoplasm. It is a dynamic structure that maintains cell shape, enables some cell motion (using structures such as flagella and cilia) and plays important roles in both intracellular transport (the movement of vesicles and organelles)The cytoskeleton has three major fibre types: Microfilaments made up of actin proteins, Intermediate filaments made of various kinds of proteins (Keratin) and Microtubules made of tubulin.
