Phototropin+All PYQS

Which LOV domain is crucial for kinase activation?

Go with B — LOV2. Under Phototropin+All, 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) LOV1; C) Both equally; D) Neither. When two options sound similar, choose the one that matches the textbook definition most tightly.

PHYTOCHROME+PYQS

PhyB is most strongly associated with regulation of:

Pick B: Shade avoidance. Thinking through PHYTOCHROME step by step rules out the lookalikes and leaves Shade avoidance. Skip these: A) Seed germination; C) Vernalization; D) Stomatal movement. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

ABC MODEL+PYQS

SEPALLATA genes belong to which class in ABCDE model?

Correct option is D, E. In ABC MODEL problems like this, the accurate statement is E; the others are common mix-ups. Not these: A) A; B) B; C) D. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
