Question: Which element(s) are highly mobile in plants?NPCaKChoose the most appropriate answer from the options given below: (Ag. Supervisor 2023)
Options:
1 and 2 only
1, 2 and 3 only
2 and 3 only
1, 2 and 4 only
✅Explanation:
-Nitrogen (N), Phosphorus (P), and Potassium (K) are highly mobile in plants, meaning they can move easily within the plant to different tissues when needed.
-Calcium (Ca), on the other hand, is less mobile in plants, primarily staying in the cells where it was deposited.
Thus, N, P, and K are highly mobile elements in plants.
