Plant bends towards the source of light on account of the movement of curvature known as
|
|
geotropism
|
|
|
thigmotropism
|
|
|
chemotropism
|
|
|
phototropism
|
Explanation:
Detailed explanation-1: -In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.
Detailed explanation-2: -Phototropism, or the differential cell elongation exhibited by a plant organ in response to directional blue light, provides the plant with a means to optimize photosynthetic light capture in the aerial portion and water and nutrient acquisition in the roots.
Detailed explanation-3: -One such response is the phototropic response-the bending of a plant organ toward (stems and leaves) or away from (roots) a directional blue light source.
