0 the growth or movement of a plant, or of a particular part of a plant, towards light or away from it --
Experiments performed were used to explore the mechanisms of both blue-light- and red-light-induced phototropism in plants.
The specific aim of this project was to investigate phototropism in plants grown in microgravity conditions without the complications of a 1-g environment.
Phototropism is one of the many plant tropisms or movements which respond to external stimuli.
Together phytochromes and cryptochromes inhibit gravitropism in hypocotyls and contribute to phototropism.
Phototropism is the effect of light on plant growth that causes the plant to grow toward or away from the light.
He worked on the neural system of insects, on phototropism and on the evolution of sight.
They are known for their strong phototropism response and helical growth of the sporangium.
There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism.
