How does most of the water move within a healthy plant body and by which path ?

Explanation

Water is absorbed along with mineral solutes by the root hairs purely by diffusion. Once water is absorbed by the root hair, it moves by two distinct path ways.
(a) Apoplast pathway (b) Symplast pathway
(a) Apoplast pathway : Apoplast is the continuous system of cell walls and intercellular spaces in plant tissues. In apoplast pathway water movement is through the cell wall without crossing membranes.
(b) Symplast pathway : Symplast comprises of network of cytoplasm of all cells inter connected by plasmodesmata. The movement of water occurs from one cell to another through plasmodesmata.
Most of the water flows in the cortex occurs via the apoplast. Since the cortical cells are loosely packed and hence offer no resistance. Endodermis radial walls are thickened with casparian strip. Passage cells allows water by symplast, through pericycle it reaches xylem.
