iodine diffused into the cell and mixed with the
starch and glucose to change color
No
The solution around the cell did not change color
Yes
The solution in the beaker was tested and changed
color after heat was added
Iodine diffused into the cell and glucose diffused out
Starch did not diffuse out of the cell because it is
too large
Small molecules diffuse into or out of the cell but larger
molecules do not

Water diffused out of the cells causing them to shrink.
The cells swell back to normal size and color lightens as
water diffuses back into the cells.

Iodine will diffuse out of the cell and glucose will
diffuse into the cell. The color change will happen in the
water in the beaker.
Plants in the area will wilt and turn brown as their cells
lose water through osmosis.
Too much water would diffuse into their cells and could
cause the cells to burst.
Osmosis
The organism would not need a contractile vacuole in salt
water because the water would naturally diffuse out.
Water diffuses out of the cells in your mouth and throat
because of the salt on the popcorn.
Our cells need glucose to create the ATP (cell respiration)
needed for life processes.
