Plants may be stationary, but they're rarely still, says biologist Roger Hangarter, creator of the website Plants in Motion
. Researchers are using time-lapse photography to study the biomechanics of plant movement. For example, in an August 2012 issue of the journal Science
, physicist Sharon Gerbode, of Harvey Mudd College, and biologist Joshua Puzey, of Harvard University, explain how they used time-lapse, mathematical modelling and a prosthetic plant to understand how cucumber tendrils twist.
