BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.

Detailed explanation-2: -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-3: -Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis.

Detailed explanation-4: -Phototropism Examples Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.

Detailed explanation-5: -(a) The growth of plant parts in response to light is known as phototropism. An example of phototropism is the growth of plant stem in the upward direction in response to sunlight.
