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.

What is the first stage of signal transduction in plants?

Describe the role of Cyclic GMP in the transduction phase.

What happens during the response stage of signal transduction?

Explain the process of phosphorylation in the context of transcription factors.

How do response proteins affect plant growth in response to light signals?
