9.Define the following terms diffusion: - Osmosis

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, aiming to balance out concentrations across a space. Imagine a drop of food coloring in water – it spreads out until the color is evenly distributed, just like how sugar dissolves in tea! Osmosis is a special kind of diffusion that involves water molecules. It occurs when water moves through a semi-permeable membrane from an area with a lower concentration of solutes (like salt or sugar) to an area with a higher concentration. Think of it as water trying to create balance; just like when you water a plant, it helps the roots absorb just the right amount of water from the soil!
