A choice chamber can be made with both dry and damp compartments to investigate the influence of humidity in woodlice movement. In a tropism response, plants can only change the direction of their growth either towards or opposite the direction of the stimulus because plants cant move. Unlike light sources, these stimuli can be harder to pinpoint and may not vary in clear gradients, making it harder to inform a directional response.
