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
The correct answer is: C
Explanation
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.
