Transport Flashcards
(26 cards)
HYPOtonic
lower concentration of solute
ISOtonic
same concentration of solute
the pressure inside a plant cell caused by water pushing against the cell wall is called _____________ pressure
turgor
the swelling and bursting of animal cells when water enters is called
cytolysis
swells up
HYPOtonic
placing plant cells on a HYPOtonic solution causes osmotic pressure to
increase
the shrinking of plant cells when water leaves so the cell membrane pulls away from the cell wall is called
plasmolysis
shrinking happens in
HYPERtonic
when water leaves a plant cell, the osmotic pressure will
decrease
the substance that dissolves to make a solution
solvent
during diffusion molecules tend to move
down the concentration gradient
when the concentration of a solute is the same throughout a system, the system has reached
equilibrium
the diffusion of water across a selectively permeable membrane
osmosis
energy for active transport comes from a cells
mitochondria
____________ transport requires energy ATP to move substances across membranes
active
the pressure exerted by water moving during osmosis
osmotic
placing an animal cell in a HYPOtonic solution will cause water to
move into cell
when molecules move down the concentration gradient it means they are moving from
high concentration to low concentration
active transport requires ____________ to move molecules across membranes
energy
________ is the molecule that provides the energy for active transport
ATP
golgi bodies use _____________ to release molecules outside the cell
exocytosis
__________ moves oxygen and carbon dioxide molecules from a high concentration to a low concentration across membranes
diffusion
the cell organelles that burn glucose and provide ATP for active transport are the
mitochondria
a small membrane sac used to transport substances during exocytosis and endocytosis
vacuole
