Sensitive Plant (Mimosa)

The leaves of this Mimosa were given a slightly more extreme heat treatment. You can see that the response starts more rapidly and progresses faster than the leaf in the previous movie. In addition, you will notice that once the leaflets close along the stimulated part of the leaf, the signal propagates further and activates motor cells at the base of the entire leaf and each leaf section to fold, followed by the progressive closing of the rest of the individual leaflets until the entire leaf has folded.

Go back to the other Mimosa movie to compare the behavior.
