Which statements correctly describe the main route that water takes as it leaves a leaf? Select all that apply.
It evaporates from the surfaces of cells inside the leaf✓الإجابة الصحيحة
It runs out of the pores as droplets of liquid
It collects as vapour in the air spaces inside the leaf✓الإجابة الصحيحة
It diffuses out through the pores of the leaf✓الإجابة الصحيحة
It passes straight out through the waxy layer of the leaf surface
الشرح
Water reaches the air inside a leaf by evaporating from the damp surfaces of the cells there, and only after that does it diffuse out through the pores as vapour. Liquid does not pour out of the pores, and the waxy layer exists precisely to stop water crossing the leaf surface, so neither of those describes the ordinary route out.
