Osmosis and diffusion glossary

Question 1

diffusion

Answer 1

the movement of particles from an area of high concentration to an area of low concentration until equilibrium (a balance) is reached

Question 2

solute

Answer 2

a substance that dissolved in a liquid(solvent) to from a solution

Question 3

solvent

Answer 3

a liquid which dissolves a substance( solute) to form a solution

Question 4

concentrated solution

Answer 4

a mixture which contains lots of dissolved solute particles

Question 5

concentration

Answer 5

the number of particles of solute in a particular volume of solvent

Question 6

dilute concentration

Answer 6

a solution which contains only a few solute particles

Question 7

isotonic solution

Answer 7

a solution which has the number of solute particles as inside the cell

Question 8

hypotonic solution

Answer 8

a solution which has a low concentration of solute particles that inside the cell

Question 9

what would happen if a cell was placed in a hypotonic solution?

Answer 9

water particles would move into the cell by osmosis.

Question 10

hypertonic solution

Answer 10

a solution which has a higher concentration of solute particles that inside the cell

Question 11

what would happen if a cell was placed in a hypertonic solution?

Answer 11

water will move out of the cell by osmosis

Question 12

osmosis

Answer 12

the diffusion(movement) of water molecules from an area of high concentration of water to an area of low concentration of water across a partially permeable membrane

Question 13

partially permeable membrane

Answer 13

a membrane which allows certain molecules to pass though it, but not others.
