Question

Root pressure is observed when absorption of water is
and loss of water is
(A) High High
(B) Low LOW
(C) High Low
(D) Low High​

Answer 1

Answer:

Option (C) High Low is the correct option.

Explanation:

• Root pressure is observed when absorption of water is high & loss of water is low.
• Absorption of water by the root is high when the solute concentration is high & water potential is low in the root cells than by the process of endosmosis water enters the root cells from the soil via root hairs.
• Loss of water is also called transpiration which causes a suction pull in which water is absorbed by the root from the soil and transported upwards through the xylem elements to compensate for the transpiration from the leaves. When transpiration is low, root pressure is maximum.

Answer 2

Answer:

Option C is the correct option.  

Explanation:

1. Root Pressure can be observed when the Absorption of Water is High and the Concentration of Water is Low.
2. Root Pressure is a pressure that develops in the Xylem sap of the roots of plants and it is maximum when the loss of minerals and transpiration loss is minimum (low) and absorption of water is high.
