Who came up with tropism?


Tropism is the directional movement response to a stimulus either towards or away from the stimulus. Tropism is generally seen in plants and some bacteria and virus. If the movement is towards the stimuli, it is positive tropism and if the movement is away from the stimulus, it is negative tropism.

Answer and Explanation: 1

Charles Darwin and his son Francis discovered the phototropic stimulus in 1880 and observed that phototropism was detected at the tip of the plant. Auxin was later discovered by F.W.Went as an evidence of the phototropic response of the plant stem.
