    Assertion (A) A cell membrane shows fluid behaviour. Reason (R) A membrane is a mosaic or composite of diverse lipids and proteins. Each of these questions contains two statements. Assertion (A) and Reason (R). Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

    A) If both Assertion and Reason are true and Reason is correct explanation of Assertion.

    B) if both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

    C) If Assertion is true but Reason is false.

    D) If both Assertion and Reason are false.

    Correct Answer: A

    Solution :

    The phospholipid that make up the phospholipid bilayer of cell membrane is like a fluid because they are constantly moving and swithcing places. The protein in the membrane are the mosaic because there is a variety of protein embedded through out the membrane. Thus both assertion and reason are true but reason is not the correct explanation of assertion.
