Question

Which one of the following elements in plants is not remobilised ?

• A. phosphorus
• B. calcium
• C. potassium
• D. sulphur

Answer 1

Answer: (B)

Calcium is the element in plants which is not mobilised. This is because it is a structural component and hence needs to be localised.
Phosphorus, Sulphur and Potassium are not structural elements and hence can be remobilised based on their need.
