Question

which of the answer choices correctly describes the movement of water across a selectively permeable membrane during osmosis?

Answer 1

There is mistake, as there is no choices typed, originally, the answer is as,  All of the descriptions given in same questions are correct and equivalent.

The movement of water across a selectively permeable membrane during osmosis is as follows;

• The water always goes from the higher concentration towards lower concentration,
• In a low solute concentration the movement of water remains towards higher solute concentration,

In the process of Osmosis only, water moves from higher concentration to lower concentration, and only across the membranes, unlike the process of diffusion,

In which, other materials also transported across membranes and to the cells, thus we can say Osmosis is a special case of the process of Diffusion.

It is seen that, the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes, which is responsible greatly for the process of Osmosis.

Until the concentration gradient of water goes to zero or the hydrostatic pressure of the water balances the osmotic pressure, the process continues.
