Question

potato cubes when placed in water become firms and increase in size​

Answer 1

Answer:

Potato cubes contain excess of salts and sugars as compared to the water in which the cubes are placed. Hence, due to endosmosis, water from the surrounding enters the potato cubes making them firm and increasing their size.

Answer 2

Answer:

Potato cells have cell sap of higher concentration than the surrounding water. As a result, endosmosis occurs in which water molecules travel to the inside of the potato cells, making them firm. Due to the inflow of water, the cells become turgid, so the potato cube becomes firm and increase in size.
