Osmosis Flashcards
define osmosis
the diffusion of water from a dilute solution to a concentrated solution through a semi permeable membrane
define dilute
high concentration of water
define concentrated
low concentration of water
define semi permeable
allows some molecules to pass through but not all
what happens if we place an animal cell in water or a dilute solution
water will diffuse into the cell, in the case of an animal cell the water moving in will cause the cell to expand and maybe even burst
what happens if we place an animal cell in a concentrated solution
water will move out of the cell causing the cell to shrink
what happens if we place a plant cell in water or a dilute solution
water will move into the cell, the cell wall prevents the plant cell from bursting, instead the cell becomes swollen, this is called turgid
what happens if we place a plant cell in a concentrated solution
water moves out of cell, causes cell to shrink, this is called flaccid
