Detailed explanation-1: -Osmosis And Diffusion Examples To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane. Examples of Diffusion: Examples of diffusion include perfume filling a whole room and the movement of small molecules across a cell membrane.

Detailed explanation-2: -Final Answer: Uptake of water by root hair and swelling of seed when put in soil are examples of osmosis.

Detailed explanation-3: -Their conclusion: It’s the nervous system that causes your digits to look like prunes. As the video puts it, “The nervous system causes the wrinkling by constricting blood vessels below the skin which causes the upper layers of skin to pucker."

Detailed explanation-4: -A phenomenon called endosmosis takes place when raisins are placed in water for few hours. When raisins are soaked in water, they swell. All this is due to the process of osmosis. The water molecules pass the cell membrane of the raisins and the raisins thus get swollen.
