Why are fresh fruits and vegetables sprinkled with water in the super market?
Sprinkling fruits and vegetable with water keeps them firm and hydrated so they seem fresh and attractive to the buyer. Why? Water is hypotonic to the plant cells. Water has fewer solutes and a higher concentration of water than the inside of the plant cells. That causes more water to diffuse into the plant cells than the amount of water that diffuses out of the cells. More water inside the cells makes them nice and firm. Memory trick: when cells are in a hypotonic solution … hyp – o – tonic makes them swell up like an O.
