|
|
DECREASE IS TURGIDITY OF GUARD CELL
|
|
|
RADIAL ORIENTATION OF CELLULOSE CELL WALL OF GUARD CELL
|
|
|
CONTRACTION OF OUTER WALL OF GUARD CELL
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Final answer: The opening of the stomatal aperture takes place by the radial orientation of cellulose microfibrils in the guard cells’ cell walls.
