Should a plant cell be kept in higher concentration solution than the environment to reach the isotonic point?

i see that in text book it is mentioned that plant cell should be turgid in order to be healthy...if so then any plant cell with respect to their environment should be in hypotonic environment? (becuz they the water molecules will move in to make it turgid) if that is so then the isotonic point of the plant cell should be ....greater than the the environment they live in (becuz their environment is hypotonic...so to establish an equilibrium (isotonic solution) its concentration should be increased)....
