Hello again, plant folks.

I am editing a high school biology lab manual that is under revision,
and came across an activity to demonstrate hydrotropism. I recall
learning in grad school about 20 years ago that roots grow toward water.
However, I understand that this has been questioned and some do not
agree that there is such a thing as hydrotropism.

Can anyone enlighten me on this point/
