SEPALLATA genes belong to which class?

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

Loss of C class gene activity converts carpels into:

Go with B — Petals. Under PSS-Sec-E-Sensory biology, 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) Sepals; C) Stamens; D) Ovules. When two options sound similar, choose the one that matches the textbook definition most tightly.

SEP1/SEP2/SEP3 triple mutants produce flowers with:

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