#floral organ identity

24 public questions tagged with this topic.

Genes specifying ovule identity belong to class:

Correct option is D, D. In PSS-Sec-E-Sensory biology problems like this, the accurate statement is D; 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.

Floral quartet model involves formation of :

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

Loss of B class gene function leads to:

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

In ABC model, class B genes specify:

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

Loss of Class C gene function leads to formation of:

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

Class A and Class C genes shows which interaction?

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

AGAMOUS (AG) gene mainly specifies:

Answer: C) Stamens and carpels. 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) Sepals; B) Petals; D) Ovules. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Class D genes mainly control development of:

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

Tetramers in Quartet model are formed by association of:

The right choice is B: Two dimers. 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) Four monomers; C) Three dimers; D) Five monomers. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

In Quartet model, functional unit regulating organ identity is:

Answer: C) Tetramer. 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) Monomer; B) Dimer; D) Pentamer. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Which of the following is NOT a MADS-box gene?

D fits best: AP2. Keep the ABCE & ABCDE MODEL +Synapdrgon flowering basics straight and AP2 stands out as the precise answer. Avoid: A) AG; B) PI; C) AP3. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Class E genes act mainly as:

Pick C: Co-factors for ABC genes. Thinking through ABCE & ABCDE MODEL +Synapdrgon flowering step by step rules out the lookalikes and leaves Co-factors for ABC genes. Skip these: A) Structural proteins; B) Hormones; D) Enzymes. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
