Vedclass · Answer

(B) In the given diagram of the root pathway,the transport of water occurs through symplastic and apoplastic pathways.$P$ represents the plasmodesmata,which are channels that traverse the cell walls of plant cells and some algal cells,allowing transport and communication between them.$Q$ represents the cortex,which is the region between the epidermis and the vascular cylinder.$R$ represents the Casparian strip,which is a band of cell wall material deposited in the radial and transverse walls of the endodermis,and is chemically different from the rest of the cell wall.

Column-$I$	Column-$II$
$P$. Cohesion	$I$. Water molecules are attracted to each other more in the liquid phase than in the gaseous phase.
$Q$. Adhesion	$II$. Attraction of water molecules to polar surfaces.
$R$. Surface Tension	$III$. Mutual attraction between water molecules.

The following figure shows the pathway of transport in the root. What are $P, Q,$ and $R$?
