Cell Transport

Passive Transport

high to low concentration

Active Transport

low to high concentration

Passive transport does not require

energy

Active transport requires

energy (ATP)

Isotonic

equal in and out of the cell

Hypotonic

more water in the cell (SWELL)

Hypertonic

less water in the cell (SHRINK)

Solute

What is being dissolved (example: salt)

Solvent

The liquid that dissolves other substances (example: water)

Solution

The liquid mixture (example: salt water)

Osmosis

Diffusion of water through a selectively permeable membrane

Facilitated Diffusion

moving from high to low concentration using a protein

Phospholipid Bilayer

A double layer of phospholipids that makes up plasma (cell) membranes.

Hydrophilic Head

Attracted to water

Hydrophobic Tails

Afraid of water

ATP

the main source of energy our cells use

Exocytosis

Process by which a cell releases large amounts of material

Endocytosis

process by which a cell takes material into the cell by infolding of the cell membrane

Protein

used for transportation of large molecules
