PROBLEM . – What about physical pressure? . AIM: Describe the process of passive transport (diffusion across the membrane).. . It is easy to say that water will move from high concentration to low concentration…but look at the cell to the right….

Why are diffusion and osmosis important?. Diffusion and osmosis are important because they provide . evidence. for the existence and movement of particles, that is, they provide . evidence.

Diffusion . is the movement of particles from an area of high concentration to an area of low concentration. When a particle moves from an area of high concentration to an area of low concentration, it is said that it is moving down its . Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Concentration gradient. Concentration Gradient - change in the concentration of a substance from one area to another.. Root Hair Cells . Roots do more than just anchor the plant in the ground, . they take up water and mineral salts . from the soil. . The surface of the cells have specialised root hair cells with long thin extensions that reach into the surrounding soil. . A2 BIOLOGY UNIT 3. Maximum mark = 90. Mean mark = 37.6. Entry = 2150. A*.
