Question

Discuss the Conditions necessary to cause water to diffuse out of a cell

Answer 1

When water molecules diffuse through a cell membrane this process is called the osmosis. Water molecules are extremely small and because of this they can slip freely through the gaps between the phospholipids in the cell membrane. And as a result, water molecules can constantly move back and forth though the cell 
membrane. This movement of water has a very important function and that is it enables cells to absorb water. 

Now for a movement of water molecules to happen, there should be a concentration gradient in the surrounding. That is, the amount of water in one side must be different on the other side.

For water to diffuse INTO the cell, the amount of water outside the cell membrane should be larger than the amount of water inside the side.
