Diffusion & Osmosis
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis is the diffusion of water molecules through a semi-permeable membrane. These processes are important for life on Earth as they help maintain homeostasis in living organisms.

Diffusion Osmosis
Diffusion: The process by which molecules or particles move from an area of high concentration to an area of lower concentration.
Osmosis: The process by which a solvent moves through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Semi-permeable membrane: A type of membrane that allows some molecules or ions to pass through it, while blocking the passage of others. This is how osmosis occurs.

Did you know?
Diffusion osmosis can be used to purify drinking water by removing contaminants. The process of diffusion osmosis is used by plants to absorb water and nutrients from the soil. Diffusion osmosis can also be used to cool down buildings and reduce the energy demand of air conditioners.

Question: How does diffusion and osmosis help a cell survive?
Diffusion is the process where molecules move from an area of higher concentration to an area of lower concentration. Osmosis is the process where water molecules move from an area of higher concentration to an area of lower concentration. Water helps the cell regulate its internal temperature and stay hydrated.
A: Create a drawing to show how diffusion and osmosis work together to help a cell. B: Explain how diffusion and osmosis work together to help a cell survive.
