Title: does gravity combined with the action of endogenous auxin affect the development of roots as seeds germinate? Post by: smokinjoe531 on Oct 14, 2012 If so, how?

Gravitropism is the easiest tropism to understand because it's common sense. All tropisms work with auxin to move either towards or away from a stimulus. The roots show a positive gravitropism as they are pulled down by gravity while the stem and leaves etc. show a negative tropism as they move away.
