The observation has been make that vines grow up trunks of trees as well as the sides of some buildings. Because these obserbvations the hypothesis states:
VINES ONLY USE STRUCTURES FOR SUPPORT
Experiment:
Under controlled conditions, vines were grown on real trees (control group-Plants 1,2,3), and artificial trees (experimental group-Plants 4,5,6). The following data was gathered over a five week period.

Plant 6: 18 cm
1) The plants that had real trees as supports grew more over a five week period.
Like Vines

Blomstring, epletre på VinesThe ones with real trees grew 22-29 cm, while the ones with the artificial trees grew 15-18 cm.
2) Vines use trees for more than just support. If that weren't true, the ones on the real and atrificial trees would grow the same amount. The three vines on the realy tree grew from 22.2%- 93.3% taller then the ones on the artificial trees.
3) I believe that the trees give the vines nutrients or other such things that would aide in the vines' growth.
