Overview
Gravitropism is a vital growth response in plants that allows them to orient themselves correctly in relation to gravity. Roots grow downward, demonstrating positive gravitropism, while stems grow upward, showing negative gravitropism. This dual response is essential for the plant's survival, ensuri...
