If anything in these experiments the negative phototropism was rather, more marked.
First, the action of the horizontal rays tending to drive the tick in a direction away from the source of light owing to the negative phototropism.
The directional polar transport of auxin mediates plant environmental responses through processes such as phototropism and gravitropism.
Light regulates three major plant processes: photosynthesis, phototropism, and photoperiodism.
The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.
One mechanism for phototropism in robotics is implementation of a light sensor where a direct feedback system allows for interaction with the environment.
His areas of expertise were photosynthesis, phototropism and algae.
There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism.
