If a fresh beetroot is cut up, the pieces washed in water and then left for an hour in a beaker of water, little or no red
pigment escapes from the cells into the water. If the beetroot
is boiled first, the pigment does escape into the water.
Bearing in mind the properties of a living cell membrane,
offer an explanation for this difference?
