In the wall of guard cell, cellulose microfibrils are arranged:
Obliquely
Transversely
Radially
Tangently
Cellulose microfibrils are oriented radially rather than longitudinally making it easier for the stomata to open.
In wall of guard cell, cellulose microfibrils are arranged
Assertion : The opening of stoma is also aided due to the orientation of the microfibrils in the cell walls of the guard cells.
Reason : Cellulose microfibrils are oriented radially rather than longitudinally, making it easier for stoma to open.
