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: -"Even mature plants bend toward the strongest light. They do this by elongating the cells of the stem on the side that is farthest from the light. This type of light-oriented growth is called phototropism, ‘’ explains Prof.

Detailed explanation-3: -The process of growing plants toward a light source is known as positive phototropism. Positive phototropism is found in the shoot system, which includes the leaves, flowers, stems, lateral buds, and other elements that extend above the ground.

Detailed explanation-4: -Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism, which is also known as ‘skototropism’.
