PHLOEM TRANSLOCATION+PYQS

Major source organ during phloem translocation in healthy plants is:

That points to D: Wheat. Compared with the other options, Wheat is the one that correctly describes the PHLOEM TRANSLOCATION concept. The wrong ones are A) Trifolium; B) Bryophyllum; C) Rice. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Which is least suitable for long-distance phloem transport?

D fits best: Reducing sugars. Keep the PHLOEM TRANSLOCATION basics straight and Reducing sugars stands out as the precise answer. Avoid: A) Non-reducing sugars; B) Mannitol; C) Galactosyl-sucrose oligosaccharides. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Most abundant component of phloem sap on overall basis is:

Water (C) is correct here. This is core PHLOEM TRANSLOCATION: once you know the definition or pathway step, Water is the clear fit. The wrong ones are A) Sugars; B) Proteins; D) Ions. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Carbohydrates are synthesized as glucose, transported as sucrose and stored as:

Go with C — Starch. Under PHLOEM TRANSLOCATION, 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) Cellulose; B) Glycogen; D) Maltose. When two options sound similar, choose the one that matches the textbook definition most tightly.

Water movement between xylem and phloem mainly occurs at:

C fits best: Source and sink regions. Keep the PHLOEM TRANSLOCATION basics straight and Source and sink regions stands out as the precise answer. Avoid: A) Root only; B) Leaf only; D) Stem nodes. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Glyphosate kills plants mainly because it is:

Go with B — Phloem mobile. Under PHLOEM TRANSLOCATION, 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) Xylem mobile; C) Non-translocated; D) Volatile. When two options sound similar, choose the one that matches the textbook definition most tightly.

PCMBS inhibits phloem loading by blocking:

That points to B: Apoplastic sucrose transport. Compared with the other options, Apoplastic sucrose transport is the one that correctly describes the PHLOEM TRANSLOCATION concept. The wrong ones are A) Symplastic pathway; C) Photosynthesis; D) Xylem flow. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Phloem unloading at sink tissues is generally:

That points to B: Energy dependent. Compared with the other options, Energy dependent is the one that correctly describes the PHLOEM TRANSLOCATION concept. The wrong ones are A) Passive only; C) Always diffusion driven; D) Independent of metabolism. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Transfer cells are specialized by presence of:

Answer: B) Wall ingrowths. For PHLOEM TRANSLOCATION, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Large vacuoles; C) Sieve plates; D) Tonoplast. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Intermediary companion cells are characterized by:

C fits best: Numerous plasmodesmata. Keep the PHLOEM TRANSLOCATION basics straight and Numerous plasmodesmata stands out as the precise answer. Avoid: A) Few plasmodesmata; B) No chloroplasts; D) Thick lignified walls. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Polymer trapping mechanism involves synthesis of:

Raffinose and stachyose (C) is correct here. This is core PHLOEM TRANSLOCATION: once you know the definition or pathway step, Raffinose and stachyose is the clear fit. The wrong ones are A) Glucose; B) Starch; D) Cellulose. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Double mutants of SWEET11 and SWEET12 show:

Sugar accumulation in source leaves (C) is correct here. This is core PHLOEM TRANSLOCATION: once you know the definition or pathway step, Sugar accumulation in source leaves is the clear fit. The wrong ones are A) Normal growth; B) Increased translocation; D) Enhanced sink strength. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
