Detailed explanation-1: -The neighbors are cooking on the grill!. is that osmosis or diffusion??? Answer: Diffusion is the correct answer.

Detailed explanation-2: -For example, when someone sprays perfume and the “scent molecules” gradually spread out in the room so that everyone can smell the perfume-that’s diffusion.

Detailed explanation-3: -In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Detailed explanation-4: -Some examples of active transport include the uptake of glucose in the intestine of the human body and the uptake of minerals or ions into the root hair cells of plants.

Detailed explanation-5: -Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.
