#guard cell photoreceptors

2 public questions tagged with this topic.

Blue light–induced stomatal opening is primarily mediated by:

Answer: C) Phototropins. For PSS-Sec-E-Sensory biology, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Phytochromes; B) Cryptochromes; D) UVR8. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Which photoreceptors regulate blue light response in guard cells?

The right choice is B: Phototropins. In STOMATA MOVEMENT, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Phytochromes; C) UVR8; D) Cryptochromes. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
