Diffusion and Osmosis

Question 1

active transport

Answer 1

the use of energy in the form of ATP to move substances across the membrane

Question 2

passive transport

Answer 2

does not require energy and makes use of diffusion and filtration

Question 3

hypotonic

Answer 3

solute concentration outside the cell is lower than inside the cell HWC/LPC to LWC/HPC (if it continues long enough, cell will burst)

Question 4

diffusion

Answer 4

particles move in a random manner, spreading evenly throughout an available space and moving from regions of high concentration to low concentration

Question 5

osmosis

Answer 5

water diffusion - from high water concentration (low particle) to low water concentration (high particle)

Question 6

filtration

Answer 6

movement of water and solutes through the membrane by fluid, or hydrostatic pressure

Question 7

isotonic

Answer 7

when the solute concentration of the water is that same as that inside the cell - the amount of water that leaves and enters the cell is equal

Question 8

hypertonic

Answer 8

water leaves cell due to osmosis - solute is more concentrated outside the cell than inside the cell HWC/LPC to LWC/HPC (cell shrinks)
