Vedclass · Answer

(B) The correct answer is $B$. When the turgidity of the two guard cells flanking each stomatal aperture increases,the thin outer walls bulge out,forcing the thick inner walls into a crescent shape. This mechanical change results in the opening of the stomata. The opening process is specifically facilitated by the radial orientation of cellulose microfibrils in the cell walls of the guard cells. This radial arrangement prevents the cells from expanding in diameter,forcing them to expand in length and curve outward,which opens the pore.
