Answer 1

Answer:

$\huge\underline\pink{\tt Hey\:Mate}$

Casparian strip serves as a boundary layer separating the apoplast of the cortex from the apoplast of the vascular tissue thereby blocking diffusion of material between the two.In many of those, the endodermis is later discarded, together with the cortex, when the periderm develops from the pericycle.

Hope it helps uh!!!
