THORAX ABDOMEN AND PELVIS

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. As discussed above, phototropic response is exclusively controlled by phots.

Detailed explanation-2: -Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism, which is also known as ‘skototropism’.

Detailed explanation-3: -Abstract. Plants have evolved a wide variety of responses that allow them to adapt to the variable environmental conditions in which they find themselves growing. 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.

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.
