#phototropin

3 public questions tagged with this topic.

PHOT2 is mainly required for phototropism under:

B fits best: High light. Keep the Phototropin+All basics straight and High light stands out as the precise answer. Avoid: A) Low light; C) Red light; D) Darkness. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

PHOT1 primarily mediates phototropism under:

That points to C: Low and high blue light. Compared with the other options, Low and high blue light is the one that correctly describes the Phototropin+All concept. The wrong ones are A) Only low light; B) Only high light; D) Red light. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Photoreceptors cryptochrome, phototropin and ZTL respond to:

Pick C: Blue/UV-A. Thinking through PSS-Sec-E-Sensory biology step by step rules out the lookalikes and leaves Blue/UV-A. Skip these: A) Red/Far-red; B) UV-B; D) Green light. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
