Light And Shadows

  1. The Venus Flytrap is one of a very small group of plants capable of rapid movement,
    The mechanism by which the trap snaps shut involves a complex interaction between elasticity, turgor and growth. In the open, untripped state, the lobes are convex (bent outwards), but in the closed state, the lobes are concave (forming a cavity). It is the rapid flipping of this bistable state that closes the trap,but the mechanism by which this occurs is still poorly understood. When the trigger hairs are stimulated, an action potential is generated, which propagates across the lobes and stimulates cells in the lobes and in the midrib between them.Exactly what this stimulation does is still debated.
    OMG! LOOK OUT SHE"S GOT A KNIFE!!!

  2. LOL !

    Well if anyone could figure out how the mechanism worked - Mr. Nolan would be the guy.
