- #40 Movement Of Water And Minerals In The Xylem
Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves. The minerals (e.g., K+, Ca2+) travel dissolved in the water. Water and minerals enter the root by separate paths which...

apoplast
Term:apoplast
Origin: Anc Greek
???-/apo(=away from)
?????? (noun)/plasma(=something formed or molded, an idol) > ??????/plasso(=create, form, mold)
literally apoplast means that thee is a distinction or detachment of cell protoplast in a plant body.
Coined:
By E. Munch (1930) in order to define the water path in plant body.
Definition:
The apoplast is the available diffusional space outside the plasma membrane serving to free flow of water, inorganic ions, sugar, plant hormones and proteins. Water in the apoplast pathway moves from cell to cell via spaces in the cellulose cell walls until it reaches the endodermis. There is also the symplast pathway in which the water moves from cell to cell in the cytoplasm via the plasma membranes and plasmodesmata.
