Caption: Gravitropism (sometimes referred to as geotropism) is plant response to earth's gravitational field. Plant stems (shoots) exhibit negative gravitropism because they respond by growing away from the gravitational attraction. Gravitropism is initiated when starch filled plastids called amyloplasts sink towards the gravitational field. This stimulates the release of the growth hormone auxin. This radish (Raphanus sp.) seedling shows a turn in its stem which occurred after its pot was tipped over. The response also occurs in the dark showing that it is not phototropism.

Release details: Model release not required. Property release not required.
