The metric grain of the apple strips ar hard before immersed in the solutions. later immersed in diff erent molarities of sucrose solution and distilled water, the texture of the apple strips becomes soft. 2. The colorize of the apple strips also changes from yellow to reddish-yellow. 2) OSMOTIC CONCENTRATION OF POTATO TISSUES Quantitative data : Mass and lengthMolarity | Average length (± 0.05)cm| Average mass (± 0.
