Detailed explanation-1: -Passive transport is diffusion of molecules across a semi-permeable membrane from an area of high concentration to an area of low concentration in order to achieve a balanced concentration.

Detailed explanation-2: -Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.

Detailed explanation-3: -In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

Detailed explanation-4: -The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Detailed explanation-5: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.
