BIOMOLECULES AND ENZYMES

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: -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: -When light comes from an angle, plants will curve toward it to get better access to the light they need to grow. Hormones in the plant’s tissues, called auxins, make cells on the dark side of the plant grow taller, bending the plant toward the light.

Detailed explanation-4: -Phototropism: The bending of growing plants towards the light is called phototropism. By orienting their leaves and stems towards light plants receive the maximum energy for photosynthesis.

Detailed explanation-5: -A plants response to light has been well documented and studied. It is known to be due to differential elongation of the cells in the plant stem. Stem cells away from the light elongate in response to special auxins (growth hormones) causing the plant stem to bend towards the light.
