These … Web• both involve movement of substances from regions of high concentration to low concentration • both travel down a gradient • both don't require energy (passive transport ) Differences •diffusion =movement of any substance, osmosis = only water • osmosis refers to movement across membrane, diffusion doesn't need a membrane Students …
WebAND OSMOSISDescribe the processes of diffusion and osmosis (i) Diffusion: This is movement of solutes into and out of the cell down the concentration gradient. (The difference in concentration between a region with a high concentration of molecules and region of low concentration of molecules) ENZYMESDescribe the characteristics of … WebThe primary differentiating factor between the two systems is the medium in which they are employed. Osmosis can only function in a liquid medium, but diffusion can occur in …
WebThe student will be able to compare and contrast the following: diffusion, facilitated diffusion, osmosis, and active transport. How molecules move through the membrane. Diffusion . is the movement of molecules from an area where the molecule is in high concentration to an area where the molecule is in lower concentration. WebDiffusion In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room.
WebThere is a major difference between them. Osmosis only occurs over a semipermeable barrier, while diffusion can occur in any solution. There are three types of passive …
