Webdiffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that … WebHere, the cell can't import glucose for free using diffusion, because the natural tendency of the glucose will be to diffuse out rather than flowing in.Instead, the cell must bring in more glucose molecules via active transport.In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its …

WebDiffusion. Diffusion is the random movement of a substance from a region of high concentration to a region of low concentration (ie: down the concentration gradient). For … Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states. One of the … See more Diffusion is an important part of many biological and chemical processes. In biological systems, diffusion occurs at every moment, … See more Diffusion is affected by temperature, area of interaction, steepness of the concentration gradient and particle size. Each of these factors, independently and collectively can alter the rate and extent of diffusion. See more Diffusion in the human body is necessary for the absorption of digested nutrients, gas exchange, the propagation of nerve impulses, the … See more WebCompletely editable in Word. This hands-on lab activity covers the osmosis, diffusion and water potential content described in the AP Biology Unit 2 Course and Exam Description.
