Osmosis.
Molecules that are large, polar, or charged generally do not pass easily through the plasma membrane. These types of molecules require transport proteins to facilitate their movement across the membrane. Examples include glucose, ions, and water.
Alcohol moves across the cell membrane by means of osmosis.
Osmosis is a movement of Water through a semiprmable membrane.
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
The process that allows movement of large molecules across a cell membrane is called endocytosis. In this process, the cell membrane engulfs the large molecules, forming a vesicle that brings them into the cell. There are different types of endocytosis, including phagocytosis for solid particles and pinocytosis for liquids. This mechanism enables cells to intake substances that cannot directly pass through the lipid bilayer of the membrane.
A selectively permeable membrane allows water molecules to pass through but restricts the movement of larger solute particles like NaCl. In osmosis, water will move from a dilute solution to a concentrated solution through the membrane, causing a net movement of water without the movement of NaCl.
