NEET Biology Photosynthesis in Higher Plants Question Bank Assertion and Reason

  • question_answer
    Assertion : The stromal thylakoids are rich in both PS I and PS II. Reason : The granal membranes are rich in ATP synthetase.

    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

    D) If both the assertion and reason are false

    E) If the assertion is false but reason is true

    Correct Answer: D

    Solution :

    The grana stacks of membranes are enriched in PS II and LHC (Light harvesting centre), while there is little ATP synthetase. On the other hand, a fraction of stroma thylakoids is rich in PS I and ATPase and poor in PS II and LHC.
