Understanding Osmosis: Diffusion of Water Through a Partially Permeable Membrane.

The video tutorial explains osmosis as the diffusion of water through a partially permeable membrane from a dilute to a concentrated solution. It describes how osmosis involves random movement of water molecules, resulting in a net movement from higher to lower water concentration until equilibrium is reached. The tutorial also covers the role of osmosis in cells, where the cell membrane acts as the partially permeable membrane, allowing water to move in and out of cells.

What is osmosis and how does it occur?

Explain the concept of a partially permeable membrane.

Describe the movement of water molecules during osmosis.

What happens to the concentrations of solutions on both sides of a membrane during osmosis?

How does osmosis relate to cell transport?
