PHYTOCHROME+PYQS

Etiolated seedlings grown in darkness show which characteristic?

Answer: C) Long hypocotyl. For PHYTOCHROME, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Short hypocotyl; B) Expanded cotyledons; D) High chlorophyll. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

PSS-Sec-E-Sensory biology

Constitutive photomorphogenic mutants show photomorphogenesis even in:

The right choice is B: Dark. In PSS-Sec-E-Sensory biology, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Light; C) Far-red light; D) Shade. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
