None of these

Vedclass · Answer

(D) Casparian strips are located in the radial and tangential walls of the endodermal cells.They are composed of water-impermeable,waxy material called suberin (often associated with lignin).Statement $I$ is incorrect because Casparian strips are found in the endodermis,not surrounding the pericycle.Statement $II$ is correct as they are made of lignosuberin.Statement $III$ is correct because by blocking the apoplastic pathway,they force water and solutes to enter the symplast to cross the endodermis.Therefore,statements $II$ and $III$ are correct,but since this combination is not provided in the options,the most appropriate choice based on the provided options is $D$ (None of these).

Choose the correct statement regarding Casparian strips:
$I$. It surrounds the pericycle.
$II$. It is made up of lignosuberin.
$III$. It limits the pathway available to water solutes,forcing them to enter the symplast.
