or away from a stimulus.

1. Positive tropism – plant grows toward
the stimulus.

positive tropism

a. Phototropism = response to light – a
positive tropism
b. Gravitropism = response to gravity
where roots show a positive tropism and
stems show a negative tropism.
Positive Tropism
Phototropism
Sunflower tropism
Negative tropism
• Charles Darwin was one of the first
to scientifically document that roots
show positive gravitropism and
stems show negative gravitropism.
That is, roots grow in the direction of
gravitational pull (i.e., downward)
and stems grow in the opposite
direction (i.e., upwards).
Example of
Geotropism in the
remaints of a cellar
of a roman villa in
the Archeologic
Park in Baia, Italy
Negative tropism
• Gravity is used to signal root growth
downwards and shoots upwards.
(Shoots also use light (phototropism)
to direct growth away from gravity.)
