Question

Which of the following elements is essential for the synthesis of chlorophyll?

• A. Calcium
• B. Magnesium
• C. Sodium
• D. Potassium

Hint:

Magnesium is at the heart of chlorophyll. Without it, photosynthesis wouldn't happen efficiently!

Answer 1

The Correct Option is B

Magnesium is the central atom in the chlorophyll molecule. Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, to drive the process of photosynthesis. The presence of magnesium in the chlorophyll molecule allows it to absorb light efficiently and capture the energy needed for converting carbon dioxide and water into glucose and oxygen. Without magnesium, plants cannot produce chlorophyll, and thus cannot carry out photosynthesis, which is essential for their survival.
