For  a plant in a hypotonic environment,
   the  inflow of water results in turgor pressure against the cell wall,
   and the cells become turgid, contributing to rigidity and support.
<P>
   In  isotonic  environments  plants  become  flaccid  (  limp ), and in
   hypertonic  environments the cell membrane pulls away from the wall in
   plasmolysis.
