What is phototrophism?

Question

What is phototrophism?

Answer 1

the tendency of an organism to move toward light=positive phototrophism, away from light= negative phototrophism

Answer 2

Phototropism (not phototrophism) is directional growth in which the direction of growth is determined by the direction of the light source. In other words, it is the growth and response to a light stimuli. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi.

One good example of phototropism is the Thale cress (Arabidopsis thaliana).

Answer 3

Tropism is response to stimuli. Photo tropism is response to light, light being the stimulus.

Example of this is helio-tropism exhibited by the sunflower which tends to follow the sun from sunrise to sunset.

Answer 4

Just venturing a guess, but  "transforming from light?"

Answer 5

Photo-tropism is the tendency of (a part of) a plant to move towards (positive photo-tropism, in case of the stem) or away from (negative photo-tropism; in case of the roots) the light.  

Answer 6

Growth or movement of a sessile organism toward or away from a source of light.  

Answer 7

its the movement of an organism (mostly plants) towards or away from light.
