Question

Describe the uptake of water from the soil by plants roots in terms of water potential gradient ?

Answer 1

Answer:

Solute potential (Ψs) decreases with increasing solute concentration; a decrease in Ψs causes a decrease in the total water potential. The internal water potential of a plant cell is more negative than pure water; this causes water to move from the soil into plant roots via osmosis..

Explanation:

Answer 2

Answer:

Essentially all of the water used by land plants is absorbed from the soil by roots. Water absorbed by roots must cross several cell layers before entering the specialized water transport tissue (referred to as xylem). Water travels to the leaves via the stem.
