Vacuole of the cortical/inner cells of the stem was hypertonic to the water; the inners/cortical cells absorbed water by osmosis; and became turgid increasing in size closing the container very tightly;
stem stopper remains the same/ does not close the container very tightly;
Boiling destroys the cell membrane of the stem cells preventing osmosis from occurring;
