Presentation on theme: "How cells move things in and out"— Presentation transcript:

1 How cells move things in and out
CELL TRANSPORT How cells move things in and out

2 Solutions __________: combination of solute and solvent
(Solution= solute + solvent) _________: substance being dissolved (ex. Salt) ____________: substance doing the dissolving (ex. Water) _____________: amount of solute in a solvent (difference in concentrations = “concentration gradient”)

3 How substances move _________________: movement across a cell membrane that does NOT require energy ENERGY

4 Types of Passive Transport
____________: Molecules move from areas of HIGH concentration to LOW concentration to create an equilibrium ____________: Diffusion of water in and out of the cell to create an equilibrium _________________: Uses carrier proteins to transport substances to create an equilibrium (Fig. 4- pg. 80)

5 Types of Solutions Isotonic: “iso”- _________
Concentration is the _______ inside and outside of the cell (Water moves in/out at _________ rate)

6 Type of Solutions Hypotonic: “hypo”- _________
Concentration is ___________outside the cell than inside (Water goes ______ the cell faster than ____)

7 Type of Solutions Hypertonic: “hyper”- ____________
Concentration is _________ outside the cell than inside (Water moves ________ of the cell faster than _______)

8 Type of Solutions- Video

9 How substances move __________________: requires energy to move substances in/out of the cells WHY? ____________________________ Used to transport substances: ____________________ _____________________: carry ________ a cell _____________________: carry ________ of a cell
