Vedclass · Answer

(B) The endodermis of the root is a critical layer that regulates the flow of water and solutes into the vascular cylinder (stele).Because of the presence of the Casparian strip (a band of suberin),the apoplastic movement of water and ions is blocked at the endodermis.Therefore,ions must enter the symplast to cross the endodermis.This allows the endodermis to actively transport ions in only one direction (unidirectionally) into the vascular tissue,preventing backflow.Thus,the correct pair is $A-$unidirectionally,$B-$suberin (which forms the Casparian strip).

Root endodermis has the ability to actively transport ions $A$ because of $B$. Choose the correct pair.
