Vedclass · Answer

(A) The assertion $(A)$ is correct because the plant regulates the movement of ions into the xylem through the selective permeability of the plasma membranes of root cells.The reason $(R)$ is also correct because the endodermal cells contain transport proteins that act as control points,allowing the plant to adjust the quantity and types of solutes that reach the xylem.Since the endodermal cells control the solute entry,$R$ provides the correct explanation for $A$.

$A -$ $A$ plant adjusts the quantity and types of solutes that reach the xylem.
$R -$ Transport proteins of endodermal cells are control points.
