OSMOSIS Flashcards
Definition of osmosis…
the movement of water from an area of high water potential to an area of low water potential lacrosse a semi permeable membrane.
What is a semi permeable membrane?
a membrane that has small holes in it which allow small molecules through it but not larger molecules.
what is the semi permeable membrane in an animal cell
the cell membrane
If a cell is in a hypertonic solution, where is the water potential higher.
inside the cell
if a cell is placed in a hypotonic solution, where is the water potential higher?
outside the cell
what will the movement of water be if the cell is placed in a hypertonic solution?
out of the cell
what will the movement of water be if the cell is placed in a hypotonic solution?
into the cell
what is it called if the water potential is the same on the inside and outside of the cell?
isotomic
negative numbers mean a ……………. water potential
low
what is it called if an animal cell bursts
lysis
what is it called if an animal cell shrinks
crenation
what is it called if a plant cell swells
turgid
what is it called if a plant cell shrinks
wilting/flaccid
