In order to keep the leaf cells of the vegetables firm and rigid, so they can look fresh and appealing, they have to be placed in a hypotonic condition i.e. an external condition with high concentration of water. To do this, a grocer in a supermarket will occasionally spray the vegetables with pure water to keep the vegetables' cell from drying out and hence lead to wilting, which would make the vegetables less appealing to customers.
