Osmosis
Biology · Secondary 3 · Hard · Osmosis
In an experiment, potato cubes are placed in a 2% sugar solution. The water potential inside the potato cells is higher than that of the solution. After 1 hour, what will most likely happen to the mass of the potato cubes?
- Their mass increases because water enters the cells by osmosis.
- Their mass decreases because water leaves the cells by osmosis.
- Their mass stays the same because no osmosis occurs.
- Their mass first increases then decreases as diffusion stops.
