The correct Answer is:
To solve the given question, we will analyze both the assertion and the reason step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "In chlorophyceae, the plant body is usually grass green." - Chlorophyceae, commonly known as green algae, typically exhibit a green color due to the presence of chlorophyll pigments. 2. **Understanding the Reason**: - The reason provided is "Members of chlorophyceae possess chlorophyll a, c, carotenoids, and xanthophyll." - Chlorophyceae primarily contain chlorophyll a and b, which are responsible for the green color. While carotenoids and xanthophyll are present, they do not primarily contribute to the green color. 3. **Analyzing the Truth of the Assertion**: - The assertion is true because chlorophyceae are indeed usually grass green due to the high concentration of chlorophyll a and b. 4. **Analyzing the Truth of the Reason**: - The reason is partially true because it correctly states that members of chlorophyceae possess chlorophyll a and carotenoids. However, it incorrectly states that they possess chlorophyll c, which is not typical for this group. 5. **Determining the Relationship**: - Since the assertion is true and the reason is true but not a correct explanation for the assertion (as it includes chlorophyll c, which is not characteristic of chlorophyceae), we conclude that the reason does not adequately explain the assertion. 6. **Final Conclusion**: - The correct option is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion. ### Final Answer: The correct option is: **If both assertion and reason are true, but the reason is not the correct explanation of the assertion.** ---
To solve the given question, we will analyze both the assertion and the reason step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "In chlorophyceae, the plant body is usually grass green." - Chlorophyceae, commonly known as green algae, typically exhibit a green color due to the presence of chlorophyll pigments. ...
