Vedclass · Answer

(D) The $Casparian$ strip is a band of cell wall material deposited in the radial and transverse walls of the endodermis,which is chemically composed of suberin.It acts as a selective barrier that forces water and dissolved solutes to pass through the plasma membrane of the endodermal cells rather than moving through the apoplastic pathway.By forcing this movement through the cytoplasm (symplastic pathway),the plant can regulate the uptake of water and minerals into the vascular cylinder (xylem).If a plant cannot produce $Casparian$ strips,it loses the ability to selectively control the entry of water and solutes into the xylem,leading to an unregulated flow.

$A$ botanist discovered a mutant plant that was unable to produce materials that form the $Casparian$ strip. This plant would be:
