Discuss the phenomenon of osmosis.why and how does the water molecules move from a region in which there are many of them to a region in which...

Osmosis is the diffusion of water through a selectively
permeable membrane. It is a type of passive transport because no additional energy must
be added for this process to occur. If there is a greater concentration of water
molecules on one side of the membrane(high solvent, low solute), and fewer molecules on
the other side of the membrane(low solvent, high solute), a concentration gradient is
established. The side where there is a greater concentration of solvent has the
probability that water molecules will more frequently collide with other water
molecules, than on the side where there are fewer molecules. Because the membrane is
permeable to water molecules, they can pass through its tiny pore spaces. Eventually,
the molecules will diffuse from high to low concentration until both sides of the
membrane have equal numbers of water molecules and osmosis will no longer occur. This is
known as an equilibrium.
