PSS- Sec-F-Transport

Reducing sugars are least suited for long-distance transport because they are:

Answer: B) Plastids. For PSS- Sec-F-Transport, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Mitochondria; C) Peroxisomes; D) Cytosol. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

PSS- Sec-F-Transport

Sucrose unloading in growing sinks generally occurs via:

C fits best: Symplastic pathway. Keep the PSS- Sec-F-Transport basics straight and Symplastic pathway stands out as the precise answer. Avoid: A) Apoplastic pathway; B) Xylem; D) Diffusion only. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

PSS- Sec-F-Transport

Velocity of polar auxin transport compared to phloem transport is:

Slower (C) is correct here. This is core PSS- Sec-F-Transport: once you know the definition or pathway step, Slower is the clear fit. The wrong ones are A) Faster; B) Equal; D) Variable. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

PHLOEM TRANSLOCATION+PYQS

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.

PHLOEM TRANSLOCATION+PYQS

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.

PHLOEM TRANSLOCATION+PYQS

Sink tissues include all EXCEPT:

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

PHLOEM TRANSLOCATION+PYQS

Source tissues in plants are generally:

Go with B — Mature leaves. 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) Roots; C) Flowers; D) Fruits. When two options sound similar, choose the one that matches the textbook definition most tightly.

PHLOEM TRANSLOCATION+PYQS

According to pressure-flow hypothesis, translocation of solutes is:

Answer: C) Passive mass flow. 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) Energy dependent throughout; B) Diffusion driven; D) Carrier mediated. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

PHLOEM TRANSLOCATION+PYQS

Pressure-flow hypothesis of phloem transport was proposed by:

The right choice is C: E. Münch. In PHLOEM TRANSLOCATION, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Darwin; B) Van’t Hoff; D) Slatyer. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

PHLOEM TRANSLOCATION+PYQS

Non-reducing sugars are preferred for translocation because they are:

Pick B: Less reactive. Thinking through PHLOEM TRANSLOCATION step by step rules out the lookalikes and leaves Less reactive. Skip these: A) Easily oxidized; C) Highly soluble; D) Rapidly metabolized. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

BASICS of PLANT+PYQS

Translocation of food in plants occurs from:

Correct option is C, Source to sink. In BASICS of PLANT problems like this, the accurate statement is Source to sink; the others are common mix-ups. Not these: A) Root to leaf; B) Sink to source; D) Stem to root. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

BASICS of PLANT+PYQS

Phloem tissue transports mainly:

Correct option is C, Sugars. In BASICS of PLANT problems like this, the accurate statement is Sugars; the others are common mix-ups. Not these: A) Water; B) Minerals; D) Lipids. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
