floating potential gradient

from higher potential to higher potential

Detailed explanation-1: -Water always moves from the system with a higher water potential to the system with a lower water potential. Solute potential (s) decreases with increasing solute concentration; a decrease in s causes a decrease in the total water potential.
Detailed explanation-2: -It means movement is from high potential to low potential.
Detailed explanation-3: -According to ncert, movement of water in symplastic pathway is down the potential gradient means high water pot. to low water pot. So it is a passive process.
Detailed explanation-4: -The difference between the water potentials of two liquids is known as the water potential gradient. Water potential is the ability of water to travel between two locations because of variations in pressure, dissolved solutes, and other factors.
Detailed explanation-5: -Solutes in the root hair cells maintain a water potential gradient, so water from the soil continues to osmose in. Vacuolar sap and cytoplasm of root hair cells contains many different components so is very dilute, as a result water osmoses down a water potential gradient into the cell from the soil.
