B1.3.2 Osmosis involves the diffusion of which molecule ____
A
All of them
B
Ions
C
Sugars
D
Water
Explanation: 

Detailed explanation-1: -Final answer: Osmosis is the diffusion of water from more concentrated solution to less concentrated solution.

Detailed explanation-2: -Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis.

Detailed explanation-3: -Osmosis is a special type of diffusion. Osmosis is defined as the movement of solvent (water in living systems) particles/ molecules from a region of their higher concentration (more dilute solution) to a region of their lower concentration (more concentrated solution), through a semipermeable membrane.

Detailed explanation-4: -OSMOSIS. Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.

Detailed explanation-5: -If a semipermeable membrane (one that is permeable to water but not a solute) separates pure water from water in which solute is dissolved, water molecules will diffuse across the membrane into the region of higher solute concentration.
