tonicity cell membrane Flashcards
what is tonicity
strength of a solution
what is a isotonic solution
concentration is the same on both sides of the membrane
what is a hypertonic solution
one side of the cell membrane is greater concentration than the other
what is it called when a cell is a hypertonic solution
the cell shrinks or crenates due to the loss of water
what is hypotonic solution
one side of the cell membrane is lesser in concentration
what happens to a cell when it’s hypotonic
it swells or burst due to the intake of water
what is it called when swells or burst due to the intake of water
lysis/hypotonic
what is endocytosis
material are brought in cell with use of vesicles that fuse plasma membrane
what is cell eating called or endocytosis do
phagocytosis
what is pinocytosis
cell drinking involves small particles
what is exocytosis
removal of a.material from a cell with vesicles that fuses membrane (opposite of endocytosis)
