Phototropism is:
when plants grow toward a light source.
a directed growth or movement in response to a stimuli.
the growth of a plant in a particular direction in response to gravity.
when plants change their growth to bend around an object or grow up a wall or tree.

a directed growth or movement in response to a stimulus.
when plants respond to touch and change their growth to bend around an object or grow up a wall or tree.
Thigmotropism is:
a directed growth or movement in response to a stimulus.
when plants grow toward a light source.
when plants grow in a particular direction in response to gravity.
