These questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following five responses.
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.

A

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

B

The correct Answer is:
To analyze the given assertion and reason, we can break down the statements and evaluate their truthfulness and relationship. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements." - This is true because eukaryotic cells, such as those in animals and plants, have a flexible structure that allows them to change shape and move. This is facilitated by their cytoskeleton. 2. **Understanding the Reason**: - The reason states that "There are three principal types of protein filaments - microfilaments, microtubules, and intermediate filaments, which constitute the cytoskeleton." - This statement is also true. The cytoskeleton is indeed made up of these three types of protein filaments, which play crucial roles in maintaining cell shape, enabling movement, and organizing the internal structure of the cell. 3. **Evaluating the Relationship**: - While both the assertion and reason are true, we need to determine if the reason provides a correct explanation for the assertion. - The assertion speaks about the ability of eukaryotic cells to change shape and move, while the reason describes the components of the cytoskeleton. Although the cytoskeleton is responsible for these abilities, the reason does not directly explain why eukaryotic cells can adopt various shapes and carry out directed movements. 4. **Conclusion**: - Since both statements are true but the reason does not adequately explain the assertion, we conclude that the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion. ### Final Answer: - The correct response is **Option B**: Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
