Explanation

Chemotropism is the movement or growth of an organism in response to chemical stimuli. The prefix 'chemo-' refers to chemical. This is commonly observed in plant roots growing toward beneficial chemicals or pollen tubes growing toward ovules. Thermotropism relates to heat, while 'Metamotropism' and 'Monomotropism' are not valid scientific terms.
