Cell Transport Flashcards
Study+Review
Movement of water across a membrane through special channels.
Osmosis
Movement of materials through a membrane from high to low concentration.
Diffusion
Movement of materials with energy from low to high concentration.
Active transport.
Movement of materials without energy from high to low concentration
Passive transport
Environment that has a lower concentration of molecules and a higher concentration of water than inside the cell causing water to enter the cell and swell.
Hypotonic
Enviroment that has a higher concentration of molecules and a lower concentration of water than inside the cell causing water to exit and the cell to shrink.
hypertonic
Environment where the concentration is equal inside the cell and outside the cell.
Isotonic
