Passive Transport:
1.Diffusion (Osmosis & Dialysis) and 2. Filtration (Hydrostatic Pressure on one side of membrane e.g. blood pressure)
Definition
The transport processes that does not require energy
Term
Active Transport: UP - low to high - 1. ION PUMP (protein complex in cell membrane) Use ATP to move substances across membranes
2. PHAGOCYTOSIS & PINCOCYTOSIS (pinch off)

Term
Filtration
Definition
Movement of water and solutes through a membrane
Term
Phagocytosis
Definition
Protective mechanism used to destroy bacteria (pinches off)
Term
Hypotonic: Cell breaks/lyse
Isotonic: Nothing will remain the same
Hypertonic: Cell will shrink/crenate and lose water
