Answer 2

Answer:

Explanation:

(i) Beaker 1: Hypotonic solution

Beaker 2: Hypertonic solution

Beaker 3: Isotonic solution

(ii) In beaker 3 the size of potato cube remains the same because of isotonic solution which has same concentration of solutes as that of potato cells. So water is neither lost or gained by the potato cells.

(iii) Cell sap of root hairs is much more concentrated than the soil solution and this causes entry of water into the root cells.

(iv) Osmosis is the movement of water molecules from a more dilute solution to a less dilute solution, through a semi permeable membrane.

(v) Cell wall is freely permeable while cell membrane is selectively permeable.
