Cell Transport Vocab

Front

A solution with equal solute concentration inside and outside the cell, resulting in no net movement of molecules.

Back

Isotonic solution

Front

No energy required; molecules move from high to low concentration; "with the gradient"

Back

Passive Transport

Front

Solute concentration is higher outside the cell; cell shrinks.

Back

Hypertonic solution

Front

Type of Passive Transport: Movement of molecules from high to low concentration, usually small molecules like CO2 and O2.

Back

Diffusion

Front

Cell membrane controls entry/exit; made of 2 layers of phospholipids, flexible.

Back

Phospholipid Bilayer

Front

Active Transport: Process releasing materials from a cell using vacuoles or vesicles.

Back

Exocytosis

Front

Solute concentration is lower outside the cell; cell gains water and swells.

Back

Hypotonic solution

Front

Type of Active Transport: Cell takes in material via membrane infoldings, creating vesicles.

Back

Endocytosis

Front

Allows some materials to pass through

Back

Semi-permeable

Front

Type of Passive Transport: Diffusion of water across a semi-permeable membrane, moving from high to low concentration.

Back

Osmosis
