Vedclass · Answer

(C) Assertion $(A)$ is correct: The inner walls of guard cells,which face the stomatal pore,are thick and elastic,which helps in the opening and closing of the stoma.Reason $(R)$ is incorrect: The cellulose microfibrils in the guard cells are oriented radially (not longitudinally) in the cell walls. This radial orientation is crucial for the mechanism of stomatal opening,as it allows the guard cells to bulge outwards when they become turgid.

$A-$ The inner wall of each guard cell,towards the pore or stomatal aperture,is thick and elastic.
$R -$ Cellulose microfibrils are oriented longitudinally in the cell walls of the guard cells.
