NEET BIOLOGY

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 a directional response that allows plants to grow towards, or in some cases away from, a source of light.

Detailed explanation-3: -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-4: -Answer: Directional movement and growth of plant in response to light is called as phototropism.

Detailed explanation-5: -Movement of plants in response to light is called Phototropism. In this case, light is a stimulus to which the plant can show two responses: i) It can move towards the light source-positive phototropism. ii) It can move away from light source-negative phototropism.
