Cell Transport Vocab

Front

A solution where the solute concentration is equal on the outside and inside of the cell, no net movement of molecules (cell stays the same = equilibrium)

Back

Isotonic solution

Front

Requires NO energy Movement of molecules from high to low concentration "with the concentration gradient"

Back

Passive Transport

Front

Solute concentration is greater outside the cell than inside the cell; cell loses water (shrinks)

Back

Hypertonic solution

Front

Type of Passive Transport Movement of molecules from high to low concentration Usually small molecules like carbon dioxide and oxygen

Back

Diffusion

Front

Cell membrane (plasma membrane), controls what enters and leaves a cell. Made of 2 layers of phospholipids, flexible.

Back

Phospholipid Bilayer

Front

Type of Active Transport Process by which materials in the cell are released outside of the cell uses vacuoles or vesicles

Back

Exocytosis

Front

Solute concentration is less outside the cell than inside the cell; cell gains water (swells)

Back

Hypotonic solution

Front

Type of Active Transport Process by which a cell takes in material into the cell by infoldings of the cell membrane Creates vesicles

Back

Endocytosis

Front

Allows some materials (not all) to pass through

Back

Semi-permeable

Front

Type of Passive Transport Diffusion of water across a semi permeable membrane Movement from high to low concentration

Back

Osmosis
