NEET BIOLOGY

Detailed explanation-1: -Iron and magnesium are the nutrients required for the production of chlorophyll.

Detailed explanation-2: -What stimulates the production of chlorophyll? To improve photosynthesis, plant growth and yield, in addition to sufficient light and water, it is also important to provide crops with the following elements: nitrogen, magnesium, iron, manganese. Only then can the plant produce chlorophyll.

Detailed explanation-3: -Magnesium fulfills several functions within the plant; it is a central component of chlorophyll which is supporting the function to absorb sunlight during photosynthesis. Magnesium acts as a phosphorus carrier in plants and is essential for phosphate metabolism.

Detailed explanation-4: -Iron is essential for the formation of chlorophyll.

Detailed explanation-5: -Mg2+ is essential for the function of many cellular enzymes and for the aggregation of ribosomes. Mg2+ concentrations also modulate ionic currents across the chloroplast and the vacuolar membranes, and might thus regulate ion balance in the cell and stomatal opening.
