Radial orientation of cellulose microfibrils in the cell wall of guard cells

Vedclass · Answer

(C) The opening and closing of the stomatal aperture are primarily controlled by the turgor pressure of the guard cells.When guard cells become turgid due to the influx of water,they expand.The cell walls of guard cells contain cellulose microfibrils that are oriented radially rather than longitudinally.This radial orientation makes the cell wall more extensible in the transverse direction,causing the guard cells to bulge outwards and pull the stomatal aperture open.Therefore,the radial arrangement of cellulose microfibrils is the key structural feature facilitating stomatal opening.

Which of the following facilitates the opening of the stomatal aperture?
