15 public questions tagged with this topic.

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.

AGAMOUS (AG) is classified as:

The right choice is C: Class C gene. 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) Class A gene; B) Class B gene; D) Class E gene. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Loss of Class A function results in absence of:

Answer: A) Sepals and petals. For ABCE & ABCDE MODEL +Synapdrgon flowering, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: B) Petals and stamens; C) Stamens and carpels; D) Carpels only. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

According to ABCDE model, ovule identity is specified by:

C + D + E (C) is correct here. This is core ABCE & ABCDE MODEL +Synapdrgon flowering: once you know the definition or pathway step, C + D + E is the clear fit. The wrong ones are A) A + B; B) B + C; D) D + E. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

ABCDE model differs from ABC model by inclusion of:

The right choice is C: Class D and E. In ABCE & ABCDE MODEL +Synapdrgon flowering, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Class E only; B) Class D only; D) Class B and C. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Most floral organ identity genes belongs to which gene family?

Answer: B) MADS-box. For ABCE & ABCDE MODEL +Synapdrgon flowering, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Homeobox; C) bHLH; D) MYB. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

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.

Stamen identity requires expression of:

That points to B: B + C + E. Compared with the other options, B + C + E is the one that correctly describes the ABCE & ABCDE MODEL +Synapdrgon flowering concept. The wrong ones are A) A + B + E; C) C + E; D) A + C. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

According to ABCE model, sepals are specified by expression of:

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

In ABCE model, Class E genes are mainly represented by:

Correct option is D, SEPALLATA genes. In ABCE & ABCDE MODEL +Synapdrgon flowering problems like this, the accurate statement is SEPALLATA genes; the others are common mix-ups. Not these: A) AP1 and AP2; B) AP3 and PI; C) AGAMOUS. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

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.

AP2 gene transcripts are detected in:

The right choice is C: All four whorls. In ABC MODEL, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Only outer whorl; B) Only inner whorl; D) Only sepals. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.
