In Greek, calling someone a plant (vlito) is like calling them an imbecile, the implication being that not much is going on upstairs. But images such as this one created by manipulating starch production in a living leaf make it clear that plants are in fact quite capable of responding to their environment. The image on this leaf was produced by occluding parts of the leaf so that the starch in its cells would be produced unevenly – in abundance where light hits the leaf and sparsely where it is shaded. For more surprising imagery created with plants and even some bacteria read Christina Agapakis’ post on Living Photography.
