What Are The 5 Tropisms And The Plant's Response To Each? Phototropism, thigmotropism, gravitropism, hydrotropism, and thermotropism are common tropic responses in plants. Plants are different than humans and animals in the way they adapt to their environment; they are sessile. Positive tropism is growth in the direction of the stimuli, while negative tropism is the growth opposite from the stimuli.
