2.1 Osmosis: The process by which water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
2.2 Facilitated diffusion: The process by which specific molecules are transported across a cell membrane by protein carriers.
2.3 Active transport: The movement of molecules across a cell membrane against their concentration gradient, requiring energy expenditure in the form of ATP.
2.4 Carbohydrates: Organic compounds made up of carbon, hydrogen, and oxygen atoms, and include sugars, starches, and cellulose.
2.5 Hydration: The process of adding water molecules to substances, often used to describe the process of dissolving a solute in water.
2.6 Phagocytic: Referring to cells, such as white blood cells, that are able to engulf and digest particles such as bacteria or debris.
2.7 Pinocytosis: A form of endocytosis in which cells engulf fluid and dissolved substances from their surroundings.
2.8 Cytoskeleton: A network of protein filaments within a cell that provides structure, support, and aids in cell movement and division.
2.9 Denaturation: The process by which proteins lose their structure and function due to changes in temperature, pH, or exposure to chemicals.
2.10 Prokaryotic cell: A type of cell that lacks a nucleus and membrane-bound organelles, found in bacteria and archaea.
