Etymologies

gravi- +‎ tropism (Wiktionary)

Examples

  • The modest light gradient experienced by the tree is counteracted by a continuous gravitational influence, known as gravitropism, which guides plant growth upward.

    Scientific American

  • A team of biologists from the University of California, Riverside has used chemical genomics to identify novel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism.
