Question

Given below are two statements. Assertion (A): The leaves are green in colour due to presence of chlorophyll. Reason (R): The green pigment present in plants is called chloroplast. Choose the most appropriate answer.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Chlorophyll is the green pigment; chloroplast is the organelle that contains chlorophyll.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question evaluates basic scientific facts about plant biology. We need to determine if leaves are green, if chloroplast is a green pigment, and how they relate.

Step 2: Detailed Explanation:
Let us analyze both statements scientifically:
• Assertion (A): Leaves of most plants are green in colour. This is a well-established and correct scientific fact.

• Reason (R): Chloroplast is described here as a "green pigment". This is scientifically incorrect. Chloroplast is a double-membrane-bound cell organelle (plastid) where photosynthesis occurs. The actual green-coloured chemical pigment found inside the chloroplasts is Chlorophyll. Thus, Chloroplast is an organelle, not a pigment.
Therefore, Assertion (A) is correct, but Reason (R) is scientifically incorrect.

Step 3: Final Answer:
Assertion (A) is correct but Reason (R) is not correct, which corresponds to option (C).
