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

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. It both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. It both Assertion and Reason are false statements.

Answer

a

Explanation

The cytoskeleton is a fibrous network made of proteins that contributes to the structure and internal organization of eukaryotic cells within the cytoplasm. It is a dynamic structure that maintains cells shape, enables some cell motion (using structures such as flagella and cilia), and plays importants 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 of actin protein intermediate filaments made of various kinds of proteins (eg keratin), and microtubules made of tubulin.
