WebbDiffusion. Diffusion is a passive process of transport. A single substance moves from a high concentration to a low concentration area until the concentration is equal across a space. You are familiar with diffusion of substances through the air. For example, think about someone opening a bottle of ammonia in a room filled with people. Webb10 maj 2024 · Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

Webb“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion in Plants Diffusion is a very important process for photosynthesis where … WebbDiffusion can happen with the molecules of the solute or of the solvent of a solution (solid, liquid or gas). Osmosis, however, only happens to the liquid solvent. For osmosis to take place, there needs to be a semipermeable membrane separating two solutions. c2 コードギアス

Webb9 sep. 2024 · What is diffusion in biology class 11? Hint: Diffusion is the process of movement of molecules from the region of higher concentration to the region of lower concentration. The change in the pressure with respect to distance is known as pressure gradient. So the diffusion is caused by the difference in the concentration. Webb6 feb. 2024 · Diffusion mainly depends on the presence of other particles. Osmosis mainly depends on the number of solute particles dissolved in the solvent. Diffusion is a passive process.
