Question

Answer 1

When does it happen?
Osmosis provides the basic procedure by which water is transported into and out of cells. Osmosis just spontaneously happens when there is an imbalance in solute concentration inside and outside the cell membrane. Osmosis provides the basic procedure by which water is transported into and out of cells.

Where does it happen?
Osmosis happens between, inside, and outside the cell membrane.

How does it happen?
Solvent molecules move from an area of high concentration to lower concentration through a semipermeable wall or membrane.

Why does it happen?
It happens in order to have solute concentration balance and to equalize the level of it between in and out of the semipermeable membrane
