NEET BIOLOGY

Detailed explanation-1: -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-2: -Auxin starts to concentrate on the shaded side of the plant instead, and as a result, the cells on the sunny side stay the same size but the cells on the shaded side grow longer. This causes the plant to tip and grow towards the light.

Detailed explanation-3: -Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of 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: -Sunlight acts as a stimulus for the growth of organisms towards the light (positive phototropism) or away from light (negative phototropism).
