|
Movement of water is always
|
|
from lower potential to upper one
|
|
|
down the potential gradient
|
|
|
floating potential gradient
|
|
|
from higher potential to higher potential
|
Explanation:
Detailed explanation-1: -In the symplastic movement, the water moves along the same water potential gradient, but across the inter-connected cytoplasm (symplast) of the cells of the root system. On the other hand, in apoplastic movement, the movement of water is through adjacent cell walls (apoplast) from the root hair cell to the xylem.
Detailed explanation-2: -Apoplastic movement is dependent on the difference in water gradient. Reason: The symplastic movement of water occurs exclusively through the intercellular spaces and the walls of the cells. Explanation: Symplastic movement of water includes the interconnected protoplast system.
