Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Differentiate between osmosis and diffusion: While both involve movement from high to low concentration, osmosis specifically refers to water movement across a membrane, whereas diffusion can involve any type of molecules.
Recognize the role of the cell membrane: The cell membrane is selectively permeable, allowing only certain molecules, like water, to pass through while blocking others.
Consider the energy requirement: Osmosis is a passive process, meaning it does not require energy input from the cell, unlike active transport which requires energy.
Identify the correct process: Given the options, osmosis is the process by which water specifically moves into or out of a cell, distinguishing it from other types of transport like active transport or facilitated diffusion.
