Which of the following statements best describes how plants use hormones during signal transduction?
A. The hormone will bind to a specific receptor in the plasma membrane. It will then trigger a series of relay proteins that alter the signal into one that will impact the cellular machinery. Once the machinery is altered a change in gene expression will occur causing a change in the physical expression of the plant.
B. The hormone will bind to a specific receptor in the plasma membrane. It will then trigger a series of relay proteins that alter the signal into one that will impact the cellular machinery. Once the machinery is altered a change in the physical expression will occur causing a change in the actual genes of the plant.
