Detailed explanation-1: -Osmosis is a special type of diffusion, namely the diffusion of water across a semipermeable membrane. Water readily crosses a membrane down its potential gradient from high to low potential (Fig. 19.3) [4]. Osmotic pressure is the force required to prevent water movement across the semipermeable membrane.
Detailed explanation-2: -They collide with one another and tend to spread out randomly. As a result, the particles tend to move from an area where they are more concentrated to an area where they are less concentrated, a process known as diffusion (dih-FYOO-zhun).
Detailed explanation-3: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.
Detailed explanation-4: -1: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration.
