WebDefinition. 1 / 14. When does diffusion occur across a cell membrane? - when the concentration of particles is different on each side of the membrane. - when the concentration of particles is equal on both sides of the membrane. - when there are no particles on either side of the membrane. - when water moves across the membrane. WebExample of diffusion in an animal cell. The cells in our body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide. If these ...

Plant and animal cells use diffusion to transport important gases ... WebCell diffusion is a type of passive transport across the cell membrane. Therefore, it does not require energy. Diffusion relies on the basic principle that molecules will tend to r each equilibrium and will therefore move from a region of high concentration to a region of low concentration. In other words, diffusion is the type of cellular ...
