Assertion: Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements.
Reason: There are three principal types of protein filaments - microfilaments, microtubules and intermediate filaments, which constitute the cytoskeleton.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

Solution

If both assertion and reason are true and reason is the correct explanation of assertion.

The cytoskeleton is a fibrous network made or proteins that contributes to the structure and internal organization 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 intra-cellular transport (the movement of vesicles and organelles, for example) and cellular division.

The cytoskeleton has three major fibre types: microfilaments made ofactin protein, intermediate filaments made or various kinds of proteins (eg keratin), and microtubules made of tubulin.
