The movement of water molecules from an area of high concentration to an area of low concentration is called
|
|
osmosis
|
|
|
diffusion
|
|
|
active transport
|
|
|
facilitated diffusion

Explanation:
Detailed explanation-1: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.
Detailed explanation-2: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Detailed explanation-3: -(A) An ideal, semipermeable membrane is freely permeable to water, but is impermeable to solute. When the membrane separates pure water on the right from solution on the left, water moves to the solution side. This water flow is osmosis.
