Plants can distinguish when touch starts and stops
Even without nerves, plants can sense when something touches them and when it lets go, a Washington State University-led study has found.

This article is wild!!! Solve calcium deficiency by touch? Jk , but still very interesting
Within 30 seconds of the applied touch to a cell, the researchers saw slow waves of calcium ions, called cytosolic calcium, travelling from that cell through the adjacent plant cells, lasting about three to five minutes. Removal of the touch showed an almost instant set of more rapid waves that dissipated within a minute.
@Moe.Red I know you will like this article. Just hope it doesn't make you want to start another experiment, groped vs nonmolested plants
