Question

One of the following is not a criterion for determining the essentiality of an element in a plant.

• A. The element is required for normal growth and reproduction.
• B. The element is distributed in all parts of the plants body equally.
• C. The element is specific and not replaceable by another.
• D. The element play a direct role in plant metabolism.

Answer 1

The correct option is B The element is distributed in all parts of the plants body equally.

Essential elements play an important role in metabolism. These elements are not equally distributed in all parts of the plants because their concentration requirement varies from location to location in a plant. Nutrients in plants are classified into macronutrients and micronutrients based on the quantity in which they are required.
