Options

A. Molecules
B. Atoms
C. Electrically charged ions
D. Parasite

Answer

C

Explanation

Plants take up nutrients as ions. Some are cations (positively charged) and other is anions (negatively charged). For example, the three major plant nutrients - * N is absorbed as ammonium ( `NH_4^(-)` a cation) or nitrate ( `NO_2^(-)` an anion).
* P is absorbed either as `H_PO_4^(-)` or `HPO_(4)^(2-)` both anions.
* K is absorbed as `K^(+)` a cation.
