The correct definition of osmosis is the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy.
The correct answer is "the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy."
Osmosis is a specific type of passive transport, which means it does not require the cell to use energy to move molecules or ions across the membrane. In osmosis, water molecules move across a semipermeable membrane from an area of higher water concentration (dilute solution) to an area of lower water concentration (concentrated solution). This movement occurs down the concentration gradient, which means the water moves from an area of high concentration to an area of low concentration until there is an equal concentration of water on both sides of the membrane. The semipermeable membrane allows only the passage of water molecules but not other solute particles.
