Osmosis

Diffusion of water molecules across a semipermeable membrane from an area of lower water concentration

Isotonic

Solution that Has an equal concentration of dissolved particles compared with another solution.

Hypertonic

Solution that has a higher concentration of dissolved particles compared with another solution.

Cell membrane

Double layer of phospholipids that forms a boundary between a cell and the surrounding environment and controls the passage of materials in and out of the cell.

Phospholipids

Molecule that forms a double layer cell membrane consists of glycerol, and 2 fatty acids

Fluid mosaic model

Model that describes the arrangement and movement of the molecules that make up a cell membrane

Selective permeability

Condition or quality of having some, but not all, materials cross a barrier or membrane

Receptor

Protein that detects a signal molecule and performs an action in response
