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

Leaves appear green because they contain a green pigment called: \[ \text{chlorophyll}. \] Chlorophyll absorbs sunlight and helps plants in photosynthesis. So Assertion (A) is correct. Now check Reason (R). Reason (R) says that the green pigment present in plants is called chloroplast. This is incorrect. Chloroplast is not the pigment. Chloroplast is the cell organelle in which chlorophyll is present. So: \[ \text{Chlorophyll}=\text{green pigment}, \] whereas: \[ \text{Chloroplast}=\text{organelle containing chlorophyll}. \] Therefore, Assertion (A) is true, but Reason (R) is false. Hence, the correct answer is: \[ \text{(A) is correct but (R) is not correct}. \]
