What effect did blue light have on stomata? Explain why you think this result was observed.
A) Blue light caused stomata to open wider. This may be because blue light activates photoreceptors that signal stomatal opening.
B) Blue light caused stomata to close. This may be because blue light inhibits the production of hormones that promote stomatal opening.
C) Blue light had no significant effect on stomatal behavior. This may be because stomata respond more to red light than to blue light.
D) Blue light caused stomata to open initially, followed by closure. This may be due to a complex interaction between blue light receptors and other environmental cues.
