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

پودوں میں مندرجہ ذیل میں سے کون سا عناصر کو دوبارہ تشکیل نہیں دیا گیا ہے؟

Potassium

Magnesium

Calcium

None of these

Calcium is not remobilized in plants because it is mainly deposited in cell walls and does not move through the phloem.

Other elements like potassium, magnesium, and phosphorus can be redistributed to younger tissues when needed.
