Important Questions on Cell Membranes and Transport

EASY
If a plant is short of water, its leaves lose their firmness and the plants wilts.
EASY
How do neutral solutes move across the plasma membrane? Can the polar molecules also move cross it in the same way? If not, then how are these transported across the membrane?
