What is the difference between diffusion and osmosis and active transport?

Best Answers

It may or may not occur across a semi permeable membrane. In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.Sep 2, 2015 read more

• Osmosis is the net movement of water down the concentration gradient, whereas active transport is the movement of substances against the concentration gradient. read more

While diffusion would allow the concentrations inside and outside of the cell to move towards equilibrium, a process called active transport helps to concentrate a solute or molecule either inside or outside of the cell. Active transport requires energy expenditure to move a molecule against its concentration gradient. read more

3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport. Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient. 4) Osmosis: is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane. read more
