Which of the following is not required for osmosis to occur?
Damm [24]

Explanation:

Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane  that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.
