movement in and out of cells

Question 1

diffusion

Answer 1

the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration

Question 2

gradient

Answer 2

the degree of inclination, or the rate of ascent or descent

Question 3

concerntation

Answer 3

the amount of a substance per defined space

Question 4

osmosis

Answer 4

osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane. (kind of diffusion)

Question 5

hypotonic solution

Answer 5

a solution containing a high water concetration in comparison to the solute concentration

Question 6

isotonic solution

Answer 6

Solutions that contain the same concentration of water and solutes as the cell cytoplasm

Question 7

hypertonic solution

Answer 7

a solution that has a high solute concentration and low water concentration

Question 8

haemolysis

Answer 8

destruction of red blood cells
