The Starch Piggy ParagraphSlide2
Today we conducted an experiment to demonstrate osmosis. Slide3
Starch “piggies”, made with dialysis
tubing
, modeled a
pseudo-cell
. Slide4
They were meant to mimic the actions of a real cell. Slide5
Inside the piggy was a starch
solution
. Slide6
When set in a solution of iodine (IKI), diffusion occurred until
equilibrium
was reached. Slide7
Dialysis tubing is semipermeable.Slide8
It was permeable to the
iodine
molecules, but not to the
starch
because the starch molecules were too large to fit through the
pores
.
