Osmosis
Biology · Secondary 3 · Hard · Osmosis
In an osmosis experiment, identical potato cubes are placed in 0 g/100 cm³ and 20 g/100 cm³ sugar solutions for one hour. The cubes in pure water gain mass. What will most likely happen to the mass of the cubes in the 20 g/100 cm³ sugar solution?
- It increases because water enters the cells by osmosis.
- It decreases because water leaves the cells by osmosis.
- It stays the same because no osmosis occurs in sugar solutions.
- It first increases then decreases because sugar enters then leaves the cells.
