Dear Colleagues,
Does anyone have a good physical demonstration of how unequal growth in a
stem can result in growth towards or away from something?  I have 2-D
pictures, but I was trying to come up with some analogy, or demo, that
shows clearly how such unequal growth can cause bending in the phototropic
response, or in twining for vines.
Thanks for any ideas you have.  Again, I'm looking for a physical or visual
demo, not a static, 2-D picture.
