Vedclass · Answer

(D) The Casparian strip is a band of cell wall material deposited in the radial and transverse walls of the endodermis. It is composed of suberin and sometimes lignin. Its primary function is to block the apoplastic pathway,forcing water and dissolved solutes to pass through the plasma membrane of the endodermal cells (symplastic pathway). This allows the plant to selectively regulate the uptake of water and minerals. Therefore,if a plant cannot produce the Casparian strip,it loses the ability to control the amount of water and solutes entering the vascular cylinder.

$A$ mutant plant is unable to produce materials or precursors that form the Casparian strip. This plant would be:
