Vedclass · Answer

(A) Most minerals cannot passively move across the cell membrane because they are present in the soil as charged particles (ions).Since the plasma membrane is impermeable to charged ions,they cannot cross the lipid bilayer by simple diffusion.Therefore,minerals must enter the root cells through active absorption,which requires energy in the form of $ATP$ and specific transport proteins.Thus,both the Assertion and the Reason are correct,and the Reason correctly explains why active absorption is necessary.

$A$ : Most minerals must enter the root by active absorption into the cytoplasm of epidermal cells.
$R$ : Minerals are present in the soil as charged particles.
