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. C. The hormone will trigger a series of relay proteins to alter the signal into one that will impact the cellular machinery. Once the signal is changed the hormone will bind to a specific receptor in the plasma membrane. It will then cause a change in gene expression to occur causing a change in the physical expression of the plant. D. None of these describes how plants use hormones during signal transduction.
