diffusion/osmosis Flashcards
what is facilitated diffusion?
carries and transports ions and other solutes across the plasma membrane
What is osmosis?
Movement of water from higher water concentration to lower water concentration through semi permeable membrane
What are essential characteristics of facilitated diffusion?
passive, specific, saturates
Types of osmotic concentration
hyper osmosis
hypo osmotic
what is osmotic concentration?
concentration of all solutes in solutions
Hyper osmotic
 Solution with a higher solute concentration
what type of transport is diffusion?
passive
Is the diffusion energy dependent or energy independent?
Energy independent(energy is not needed)
what is diffusion?
Random motion causes a net movement of substance from regions of high concentration to regions of low concentration
what is gas diffusion?
molecules are able to go through a phospholipid bilayer 
Cell transport channels are?
selectively permeable
Hypo osmotic
solution with the lower solute concentration
Osmotic concentration in plant cells
cell body shrinks (hyper)
turgid cell (hypo)
Turgid Plant Cells
great for plant cells
thrive in hypo osmotic solution
love the water
cell wall will not break
