How does phototropism occur in plants


Q. No. 6: How does phototropism occur in plants?
Ans: Environmental triggers such as light will change the directions that plant parts grow in. These directional, or tropic, movements can be either towards the stimulus, or away from it. So, in two different kinds of phototropic movement, shoots respond by bending towards light while roots respond by bending away from it.
