Detailed explanation-1: -Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
Detailed explanation-2: -Osmosis, diffusion and facilitated diffusion are some of the examples of passive transport.
Detailed explanation-3: -Furthermore, osmosis requires a semi-permeable membrane, while diffusion does not. The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food colouring is added to a glass of water, where eventually, the entire water content becomes coloured.
Detailed explanation-4: -Water, which can quickly pass through the membrane via channel proteins, will begin to leave the cell at a higher rate than it enters, with a net movement to the area with a high concentration of A, thus lowering the concentration. This is an example of osmosis.
