Signal Transduction: Light Induced Cellular Change

The video explains how light affects plant movement, flowering, and growth through signal transduction. This process involves three stages: reception, where light signals are received by photoreceptors; transduction, where intracellular pathways are activated; and response, where transcription factors are activated, leading to protein synthesis. These proteins, in turn, trigger specific plant responses such as stem bending and flower bud initiation.
