What is the role of blue light in terms of stomatal study?
a.) Blue light activates a proton-pumping ATPase in the guard cell plasma membrane and leading to stomatal opening
b.) blue-light stimulation lowers the pH of the apoplastic space surrounding the guard cells, and generates the driving force needed for ion uptake and stomatal opening
c.) The sensitivity of guard cells to blue light increases as a function of their zeaxanthin concentration
d.) npq1 mutant opens at higher fluence rates of blue light, whereas the phot1/phot2 mutant fails to show any blue light–stimulated opening
