Section 1- Homostasis & Transport Flashcards
diffusion
movement of molecules from an area of high concentration to lower concentration
equilibrium
there is no longer a net movement in any direction
osmosis
diffusion of water
turgor pressure
pressure that water molecules exert against the cell cell in hypnotic solution
passive diffusion
diffusion or movement that is accomplished without energy.
substances that can pas through a cell membrane by diffusion
glucose
the contractile vacuole of paramecium should be active when the paramecium is in a
hypotonic environment
when a human red blood cell is placed in a hypotonic environment it will undergo
cytolysis
facilitated diffusion is often used to transport molecules that
are not soluble in lipids
