Active Transport transport that requires a cell to expend its own energy to pump a molecule across the membrane. Movement of molecules from areas of low.
Section 4-1 What is homeostasis? Cells maintain homeostasis by controlling the movement of substances across the cell membrane.
Cell Membrane Maintains homeostasis by regulating the movement of molecules in and out of the cell.
Diffusion and Osmosis. The Cell Membrane The cell membrane is: Selectively permeable Permeable = Pass through (Latin) Cell membrane = Gate-Keeper.
Vocabulary Words Solution Solute Solvent Concentration Homeostasis Hypertonic Hypotonic Isotonic Permeable.
Diffusion, Osmosis and the SF Bay Solutions 1.Define solution A homogeneous mixture in which one substance is dissolved in another. Ex. Kool-aid, saltwater.
Diffusion & Osmosis. Define Diffusion The movement of molecules from a area in which they are highly concentrated to a area in which they are less concentrated.
