When the plant has water------> solvent in surrounding area of root is higher than root epidermis
-------------> solvent (water + minerals) move from a region of higher concentration to a region
of lower concentration through cell membrane, which is semi-permeable. This phenomenon is
known as osmosis. This solvent moves from root epidermal cells to root cortex because now
solvent concentration in root cortex is lower than that in root epidermis------------> to root
xylem-------> to shoot xylem------> to leaves. This phenomenon is known as Transpiration pull-
cohesion- adhesion theory. It is important to note that osmotic pressure, solute potential,
cohesion and adhesion forces, and transpiration pull, all, are collectively important in transport of
this water from soil to plant leaves.
On the other hand, when water is not there------> solvent does not move from soil to plant
epidermis------> infact solvent moves from plant epidermal cells to soil because of exosmosis.
Exosmosis occurs because solvent is higher is plant cells in comparison to the surroundings. So,
the plant wilts.
