Term
osmosis is the movement of
Definition
water
Term
what does passive transport mean?
Definition
it means it doesn't require energy to take place.
Term
water travels from
Definition
high to low water concentration
Term
pick the correct statement
Definition
solutes are dissolved into solvents
Term
a low water concentration means
Definition
a high solute concentration
Term
is it true water moves into a higher solute concentration
Definition
yes
Term
a high solute concentration means a
Definition
low water concentration
Term
water will move to the side of the membrane where there is
Definition
higher concentration of solutes
Term
what does semipermeable mean in reference to the cell membrane?
Definition
it means that it allows certain things to pass through into the cell membrane and not others
Term
what happens when salt is added to one side?
Definition
the water molecules move from low solute to high solute side
Term
water will stop moving through the cell membrane completely once the concentration of water is the same on both sides
Definition
true
Term
what does hypertonic mean in relation to the concentrations?
Definition
hypertonic means there is a high solute concentration
Term
if you were to compare hypotonic to hypertonic, how do they compare to each other?
Definition
they compare to each other because they both have a solute concentration just higher and lower
Term
the side with more solutes is
Definition
hypertonic
Term
what does isotonic mean?
Definition
isotonic means equal sides of solute
Term
how would you differentiate between hypertonic, hypotonic, and isotonic and their effect on blood cells?
Definition
i know hyper means more, hypo means less and iso means equal so that is how i tell them apart. the hypertonic effect on blood cells makes them swell. the isotonic effect makes it a normal red blood cell and hypotonic makes it shrinken
Term
if object a is hypotonic and object b is hypertonic, where and why would water move between the two objects?
Definition
object a water would move into object b because it has higher solute concentration and object b water would stay there because they stay wherever the higher solute concentration is.
