Question

Four equal strips A,B,CandD were cut from a potato whose cell sap concentration was 28.5%sugar. The strips were placed in sugar solution of different concentration as follows A-10% B-15% C-25% and D-35%

(a) what changes would you expect in strips A and D?
(b). Account for the changes in A and D

Answer 1

Strip A would shrivel due to water loss in a 10% sugar solution, while Strip D would become plump due to water gain in a 35% sugar solution.

Step-by-step explanation:

Strip A, which was placed in a 10% sugar solution, would likely lose water and become shriveled. This is because the sugar concentration in the surrounding solution is lower than the cell sap concentration, causing water to move out of the potato cells through osmosis.

On the other hand, Strip D, which was placed in a 35% sugar solution, would likely increase in size and become plump. This is because the sugar concentration in the solution is higher than the cell sap concentration, causing water to move into the potato cells through osmosis.
