Cellular Transport PPT notes What must cells take in to survive? ________________________________________________________ What part of the cell allows it to take in nutrients and water? ____________________________________ Does it have another name? What is the cell membrane made of? ______________________________________________________ What is the process for cells to move substances through the cell membrane? _____________________ Two Types of Transport Passive Transport What is Diffusion or Passive Transport? 1. _________________________________________________________________________________ 2. _________________________________________________________________________________ 3. _________________________________________________________________________________ The purpose of diffusion is to reach _______________________________________________________ Types of Passive Transport Osmosis Facilitated Diffusion Explain what is happening during osmosis. The _______________ molecules are moving from _________ concentration to _________ concentration in order to reach _________________________. In other words…. Help Wanted! Explain facilitated diffusion: _______________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ OBSERVATIONS OF OSMOSIS 80% H2O 80% H2O 100% Distilled Water 80% Water 20% Dissolved Substances 80% H2O 70% Water 30% Dissolved Substances What is a Hypertonic solution? What happens to the cell in this solution? What is a Hypotonic solution? What happens to the cell in this solution? What is an Isotonic solution? What happens to the cell in this solution?

Cell membrane Proteins and lipids Active and Passive Diffusion a. b. c. d. two types of transport movement of water across a membrane movement of substances across a membrane part of the cell that regulates what goes in and out ___ ___ 5. 6. Osmosis Facilitated diffusion e. f. movement assisted with channel proteins. two components of the cell membrane ACTIVE TRANSPORT How is Active Transport different from Passive Transport? 1. _______________________________________________________________________________ 2. _______________________________________________________________________________ 3. _______________________________________________________________________________ Types of Active Transport Enters the cell Engulfs particle Exits the cell Forms Vacuole Review energy concentration gradient passive transport active transport What part of the cell is used to bring in particles? ____________________________________________ How does a cell (including white blood cells) take in LARGE particles? ___________________________ How does a cell take in small or liquid particles? _____________________________________________
