In absence of COP1 in nucleus, plants show:

B fits best: Photomorphogenesis. Keep the PSS-Sec-E-Sensory biology basics straight and Photomorphogenesis stands out as the precise answer. Avoid: A) Skotomorphogenesis; C) Delayed flowering; D) Dwarfism. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Floral quartet complexes bind DNA through which domain?

Go with B — MADS domain. Under ABCE & ABCDE MODEL +Synapdrgon flowering, 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) Homeodomain; C) bZIP domain; D) HLH domain. When two options sound similar, choose the one that matches the textbook definition most tightly.

Carpel identity is specified by:

D fits best: C + E. Keep the ABCE & ABCDE MODEL +Synapdrgon flowering basics straight and C + E stands out as the precise answer. Avoid: A) A + E; B) A + B + E; C) B + C + E. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Floral meristem identity genes include:

Pick A: AP1 and LFY. Thinking through ABC MODEL step by step rules out the lookalikes and leaves AP1 and LFY. Skip these: B) AP3 and PI; C) AG and SEP; D) PI and AP2. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
