Vedclass · Answer

(C) Plant nutrients are classified into two categories based on their quantitative requirements: macronutrients and micronutrients.$1$. Macronutrients are required in large amounts (usually $10 \ mmol \ kg^{-1}$ of dry matter or more).$2$. Micronutrients or trace elements are required in very small amounts (less than $10 \ mmol \ kg^{-1}$ of dry matter).$Mg$ (Magnesium) is a macronutrient because it is a constituent of the chlorophyll molecule and is involved in the activation of many enzymes.$Cu$ (Copper),$Mn$ (Manganese),and $Cl$ (Chlorine) are all essential micronutrients required by plants in small quantities.Therefore,$Mg$ is the correct answer as it is not a micronutrient.
