Study the illustration. The small blue spheres represent water molecules.

In which direction will water molecules move across the membrane?


Water will move from A to B.


Water will move from B to A.


There will be no net movement of water.

Respuesta :

Given the illustration shown in the image attached to this answer, water molecules will move from B to A.

Osmosis is defined as the movement of water molecules across a semi - permeable membrane from a region of higher concentration to a region of lower concentration. Osmosis usually occurs across the cell membrane.

The cell membrane is an example of a semi - permeable membrane. Hence, water moves from B where it is at a higher concentration to A where it is at a lower concentration according to the definition of osmosis.
