BIOMOLECULES AND ENZYMES

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: -Photomorphogenesis, also defined as light-regulated plant development molecular signaling intermediates, are formed in response to the activation of photoreceptors by light. The photomorphogenic physiological responses are germination, de-etiolation, shade avoidance, circadian rhythm, and flowering.

Detailed explanation-3: -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-4: -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-5: -Phototropism is the movement of plant parts in response to light. Thus, the stimulus for phototropism is “Light”.
