Detailed explanation-1: -Positive phototropism is growth towards a light source; negative phototropism is growth away from light.

Detailed explanation-2: -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. As discussed above, phototropic response is exclusively controlled by phots.

Detailed explanation-3: -Phototropism is the movement of plant parts in response to light. Thus, the stimulus for phototropism is “Light”.

Detailed explanation-4: -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-5: -Phototropism is the movement of plants towards or away from light. If the plant part moves towards the light it is called as positive phototropism. If the plant part moves away from the light it is called as negative phototropism.
