Which of the following correctly describes the movement of water across a selectively permeable membrane during osmosis.
1. the water will move from high water concentration to low water concentration.
2. the water will move from low solute concentration to high solute concentration.
3. either of these descriptions is correct and equivalent.

The correct answer is 3  Either of these description is correct and equivalent.

Explanation:

Osmosis is one of the most important membrane transport process in both plant cell and animal cell .The process reqires a semipermeable membrane to carry out the transport of various substance such as water.

              Water is transported from the region of high concentration to the region of low concentration untill the solute contentration become same in both sides.
