What is Gravitropism?
'''Gravitropism''' (also known as '''Geotropism''') is a turning or growth movement by a plant, [[fungus]], or animal in response to [[gravity]]. It is a general feature of all higher and many lower plants and also in other [[organism|organisms]]. [[Charles Darwin]] was one of the first people to say that roots grow [[wikt:downward|downward]] and stems grow [[wikt:upward|upward]] in response to gravity. {{biology-stub}} [[Category:Plant physiology]]
