The diagrams above are illustrations of an experimental set-up to demonstrate a type of tropic response in plants. The type of response demonstrated is
phototropism
geotropism
hydrotropism
thigmotropism
Penjelasan
From the first diagram, you notice the roots of the plants bending towards the porous water pot, hence this is a form of response in the direction of the stimuli of the water. This is a form of hydrotropism.
