A maize crop is successfully growing in a field in which the water potential of the soil is-40 KPa.What is the most likely water potential of the cell sap in the root hair cell?
|
|
-60 KPa
|
|
|
-40 KPa
|
|
|
-20 KPa
|
|
|
0 KPa

Explanation:
Detailed explanation-1: -So, the correct answer is ‘False’.
Detailed explanation-2: -So, the correct answer is ‘-1 to-4 atm’
Detailed explanation-3: -Water always moves from an area of high water potential to an area of low water potential, i.e., from less negative to more negative. During water absorption by root hair, the water movement is possible if water potential of vacuolar sap is lower than root hair. Q.
Detailed explanation-4: -A root hair contains cell sap which has a higher concentration of salts as compared to the soil water. Hence the root hair cells absorb water from the soil by endosmosis.
