The growth of a plant part due to chemical stimulus is known as chemotropism or Chemotropism is the movement of a part of the plant in response to a chemical stimulus. The growth of pollen tube towards the ovule induced by a sugary substance as stimulus. This is an example of positive chemotropism.
