Osmosis is basically the process of solvent molecules moving through a permeable membrane into a region of high amounts of solute concentration. Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, critical liquids, and sometimes gases.
When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. If the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell.
So what would happen to a solute concentration of a solution surrounding a cell,the water molecules would move and not be there.This affects our world because animals and plants that are not adapted to salt water may have a low salt content, and become dehydrated when placed in salt water. Active transport is the movement of a molecule to across a cell membrane in the direction against their concentration gradient, moving from a low concentration to a high concentration.
