Detailed explanation-1: -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-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: -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-4: -Phototropism, or the differential cell elongation exhibited by a plant organ in response to directional blue light, provides the plant with a means to optimize photosynthetic light capture in the aerial portion and water and nutrient acquisition in the roots.

Detailed explanation-5: -Phototropism is the directional response of a plant that allows the plant to grow towards or in some cases away from the light. Process of phototropism: Leaf tips and stem tips have a hormone called auxin which is sensitive to light. It allows the plant to positively grow towards the light source.
