For example, phototropism is the plant’s response to stimulus, i.e. sunlight. How do plants respond to external stimuli 10? Plants produce hormones in response to external stimuli. WebTropic responses result from differential growth. Phototropism is a blue-light-dependent response controlled by the action of specific blue light photoreceptors called phototropins. Gravitropism is dependent on the presence of starch-filled plastids (amyloplasts) in specialized cells.
