Given below are two statements:
Statement I: Light reaction takes place in the stroma.
Statement II: Dark reaction takes place in grana.
In light of the above statements, choose the most appropriate answer from the options given below:
Statement I: Light reaction takes place in the stroma.
Statement II: Dark reaction takes place in grana.
In light of the above statements, choose the most appropriate answer from the options given below:
Show Hint
- Light reaction: Thylakoid membranes (grana).
- Dark reaction: Stroma of chloroplasts.
- Remember: Light in grana, Dark in stroma.
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is correct but Statement II is false
- Statement I is incorrect but Statement II is true
The Correct Option is B
Solution and Explanation
This question tests knowledge of the sites of light and dark reactions in photosynthesis.
Step 2: Detailed Explanation:
Statement I:
Light reaction takes place in the thylakoid membranes (grana).
It does not occur in the stroma.
Thus, this statement is false.
Statement II:
Dark reaction (Calvin cycle) takes place in the stroma.
It does not occur in grana.
Thus, this statement is false.
Step 3: Final Answer:
Thus, both statements are false, which corresponds to option (B).
