The gene NPH1 was later renamed as:

Pick C: PHOT1. Thinking through Phototropin+All step by step rules out the lookalikes and leaves PHOT1. Skip these: A) PHOT2; B) CRY1; D) ZTL. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Phototropins are plant photoreceptors sensitive to:

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

Correct order of water potential in plant is:

Go with B — Ψsoil > Ψroot > Ψstem > Ψleaf > Ψatmosphere. Under WATER POTENTIAL, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Ψleaf > Ψroot > Ψsoil; C) Ψroot > Ψsoil > Ψleaf; D) Ψatmosphere > Ψleaf > Ψroot. When two options sound similar, choose the one that matches the textbook definition most tightly.
