NEET BIOLOGY

Detailed explanation-1: -Iron and magnesium are the elements that are required for the synthesis of chlorophyll in plants. Hence, the correct answer is option (C).

Detailed explanation-2: -Mg2+ is the central atom of the chlorophyll molecule, and fluctuations in its levels in the chloroplast regulate the activity of key photosynthetic enzymes. Relatively little is known of the proteins mediating Mg2+ uptake and transport in plants.

Detailed explanation-3: -Iron and magnesium are essential for the synthesis of chlorophyll of plants.

Detailed explanation-4: -Chlorophyll consists of a porphyrin ring-a molecule made of carbon, nitrogen and hydrogen-attached to a long hydrocarbon tail. At the center of the porphyrin ring, a magnesium ion stabilizes the chlorophyll molecule and transfers electrons down an electron transport chain to drive the photosynthetic process.
