Phototropin+All PYQS

Phototropin-mediated stem bending occurs due to redistribution of:

Go with B — Auxin. 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) Cytokinin; C) Gibberellin; D) ABA. When two options sound similar, choose the one that matches the textbook definition most tightly.

ABC MODEL+PYQS

Which genes constitute class B in ABC model?

AP3 and PI (B) is correct here. This is core ABC MODEL: once you know the definition or pathway step, AP3 and PI is the clear fit. The wrong ones are A) AP1 and AP2; C) AG and SEP; D) LFY and AP1. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

ABC MODEL+PYQS

Which genes constitute class A in ABC model?

That points to C: AP1 and AP2. Compared with the other options, AP1 and AP2 is the one that correctly describes the ABC MODEL concept. The wrong ones are A) AP3 and PI; B) AG only; D) AP2 and AG. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
