Vedclass · Answer

(A) - Statement $A$ is correct: Nitrogen is primarily taken up by plants as inorganic ions ($NO_3^-$ or $NH_4^+$),but it is transported in the xylem sap largely in organic forms such as amino acids and amides.- Statement $B$ is incorrect: The movement of nutrients in the phloem is multidirectional,not unidirectional. This is because the source (where sugar is produced) and the sink (where sugar is consumed or stored) can change depending on the plant's needs and developmental stage.

$A$. Much of the nitrogen in xylem sap is carried in organic form.
$B$. In phloem,the movement of nutrients is always unidirectional.
