, Vocabulary
• Active Transport
• Osmosis • Endocytosis
• Diffusion • Exocytosis
• Facilitated Diffusion • Protein Pumps
• Osmotic Pressure
• Isotonic
• Hypertonic
• Hypotonic
, Background Info…
• Every living cell contains a liquid interior
(cytoplasm) and is surrounded by a liquid.
• The cell (plasma) membrane separates what is
inside the cell from what is outside of the cell
