B1.7 osmosis

Question 1

what is a dilute solution

Answer 1

–High concentration of solvent
–Low concentration of solute

Question 2

what is a concentrated solution

Answer 2

–Low concentration of solvent
–High concentration of solute

Question 3

what is a partially permeable membrane

Answer 3

membrane that only lets some types of particles through

Question 4

what is osmosis

Answer 4

the diffusion of water from a high concentration of water (dilute solution) to a low concentration of water (concentrated solution) through a partially permeable membrane

Question 5

what does isotonic mean

Answer 5

if the concentration of solutes in the solution outside the cell is the same as inside the cell, the solution is isotonic to the cell

Question 6

what does hypertonic mean

Answer 6

If the concentration of solutes in the solution outside the cell is higher than inside the cell, the solution is hypertonic to the cell.

Question 7

what does hypotonic mean

Answer 7

–If the concentration of solutes in the solution outside the cell is lower than inside the cell, the solution is hypotonic to the cell.
