Question

Which of the following is the criteria for selecting essential elements / minerals for plants?

• A. Life cycle is incomplete without it
• B. Non replaceable
• C. Metabolism (necessary for it)
• D. All of the above

Answer 1

The correct option is D All of the above

Plants absorb a number of mineral elements but all of them are not essential for them. The criteria of essentiality is that the mineral should be absolutely essential for plant and cannot be substituted by any other element. The element should directly participate in the plant metabolism. The plant cannot complete its life cycle without that element.
