Detailed explanation-1: -One important light response in plants is phototropism, which involves growth toward-or away from-a light source. Positive phototropism is growth towards a light source; negative phototropism is growth away from light.
Detailed explanation-2: -Examples: Curving of the stem toward sunlight (Positive phototropism) Movement of root away from the light inside the soil (Negative phototropism)
Detailed explanation-3: -In biology, phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.
Detailed explanation-4: -Phototropism is the growth or movement response of a cell or an organism to light. The growth response may be positive or negative. A positive phototropism is when the growth of an organism is towards the source of light.
