Detailed explanation-1: -Phototropism is the ability of the plant to re-orient the shoot growth towards a direction of light source. Phototropism is important to plants as it enhances the ability of plants to optimize their photosynthetic capacity.

Detailed explanation-2: -Phototropism is the phenomenon by which the plant bends in the direction of light. Light is required by the plants to stimulate energy production by the process of photosynthesis.

Detailed explanation-3: -Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism, which is also known as ‘skototropism’.
