Detailed explanation-1: -thus the correct answer is diffusion.

Detailed explanation-2: -Osmosis can only function in a liquid medium, but diffusion can occur in all three mediums (solid, liquid and gas). Furthermore, osmosis requires a semi-permeable membrane, while diffusion does not. The intake of water in plants is an example of osmosis.

Detailed explanation-3: -Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane.

Detailed explanation-4: -When placing a red blood cell in any hypertonic solution, there will be a movement of free water out of the cell and into the solution. This movement occurs through osmosis because the cell has more free water than the solution.

Detailed explanation-5: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
