Assertion: Magnesium is important in photosynthesis and carbohydrate metabolism.
Reason : `Mg^(+ +)` is involved in the synthesis of nucleic acids

Options

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

Answer

B

Explanation

Magnesium is absorbed by plants in the form of divalent magnesium ion `(Mg^(2+))`. It is a constituent of the ring structure of chlorophyll responsible for photosynthesis to occur. It is required for the binding of ribosome subunits during protein synthesis. It is involved in the synthesis of DNA and RNA.
