Do Plants Move? Intentionally?

 

Plant Movement and Foraging

Since Darwin, biologists have been aware that plants behave but it has been an under-appreciated phenomenon. Plants display “behaviors:  foraging for light, nutrients, and water by placing organs where they can most efficiently harvest these resources. Plants also adjust many reproductive and defensive traits in response to environmental heterogeneity in space and time. small herbivores and expose larger ones to protective thorns.



Bramble Travels:

Plants are able to move. The bramble is an aggressive example: it advances forcefully from side to side and, once settled on its course, there is little that can stand in its way. 

When its location becomes exposed, it shifts at great speed to another one with the assistance of wind — and it is this that allows many forms of vegetation to distribute their seeds. While not strictly a plant, the spores of fungi are also spread in a similar fashion as 'parachutes'.

Interesting... isn't it?
