why is it adaptive for plants to respond to gravity in their growth patterns?
Example of Gravitropism in the remains of a cellar of a Roman villa in the Archeologic Park in Baia, Italy. Geotropism (also known as gravitropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms.bundant evidence demonstrates that roots bend in response to gravity due to a regulated movement of the plant hormone auxin known as polar auxin transport (Swarup et al., 2005). This was described in the 1920s in the Cholodny-Went model.
