Question

Water enters into the root hair from the soil in its normal condition because the osmotic pressure of the soil solution
1) Remains lesser than that of root hair sap.
2) Remains equal to that of root hair sap.
3) Remains higher than that of root hair sap.
4) And that ot root hair sap remains zero.


Answer the above question with explanation.​

Answer 1

Explanation:

The soil solution is a dilute solution of minerals. Because minerals i.e., solutes are present in low concentration in soil solution, the osmotic pressure of soil solution is low. Thus, it is hypotonic as compared to the solution in cell sap. ... Hence, plant roots are able to absorb water easily from soil.
