MINERAL Transport+PYQS

Nickel is essential as a component of enzyme:

Urease (B) is correct here. This is core MINERAL Transport: once you know the definition or pathway step, Urease is the clear fit. The wrong ones are A) Nitrate reductase; C) Nitrogenase; D) RuBisCO. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Molybdenum deficiency may induce deficiency of:

Correct option is B, Nitrogen. In MINERAL Transport problems like this, the accurate statement is Nitrogen; the others are common mix-ups. Not these: A) Phosphorus; C) Potassium; D) Calcium. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Magnesium deficiency shows chlorosis first in:

Correct option is B, Older leaves. In MINERAL Transport problems like this, the accurate statement is Older leaves; the others are common mix-ups. Not these: A) Young leaves; C) Roots; D) Flowers. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Calcium deficiency primarily affects:

B fits best: Young meristems. Keep the MINERAL Transport basics straight and Young meristems stands out as the precise answer. Avoid: A) Older leaves; C) Mature leaves; D) Seeds. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Potassium deficiency mainly affects:

Older leaves first (B) is correct here. This is core MINERAL Transport: once you know the definition or pathway step, Older leaves first is the clear fit. The wrong ones are A) Young leaves first; C) Roots only; D) Flowers only. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Iron deficiency causes:

Go with B — Interveinal chlorosis of young leaves. Under MINERAL Transport, 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) Uniform chlorosis; C) Necrosis of old leaves; D) Leaf curling. When two options sound similar, choose the one that matches the textbook definition most tightly.

Micronutrients are required approximately in:

Answer: B) 100 mg/kg dry matter. For MINERAL 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) 1000 mg/kg dry matter; C) 10 mg/kg dry matter; D) 1 mg/kg dry matter. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

Mineral ions are unloaded at sink tissues mainly by:

Correct option is A, Diffusion or active transport. In MINERAL Transport problems like this, the accurate statement is Diffusion or active transport; the others are common mix-ups. Not these: B) Only diffusion; C) Only mass flow; D) Osmosis. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
