It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. But if plants all have similar stimuli, why are there so many different stem shapes? Why does a weeping willow grow downwards while nearby poison ivy shoots upwards?
Using simple mathematical ideas, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) constructed a framework that explains and quantifies the different shapes of plant stems.
The research is published in the Journal of the Royal Society Interface...
