#plant cell MCQ

PSS- Sec-F-Transport

Hechtian strands during plasmolysis are:

Correct option is C, Maintained. In PSS- Sec-F-Transport problems like this, the accurate statement is Maintained; the others are common mix-ups. Not these: A) Destroyed; B) Lost permanently; D) Converted to pits. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

WATER POTENTIAL+PYQS

A plant wilts when turgor pressure becomes:

Zero (C) is correct here. This is core WATER POTENTIAL: once you know the definition or pathway step, Zero is the clear fit. The wrong ones are A) Maximum; B) Negative; D) Positive. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

WATER POTENTIAL+PYQS

Positive pressure potential is also called:

C fits best: Turgor pressure. Keep the WATER POTENTIAL basics straight and Turgor pressure stands out as the precise answer. Avoid: A) Tension; B) Matric force; D) Osmotic pressure. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

BASICS of PLANT+PYQS

Turgor pressure is exerted by:

Protoplast on cell wall (B) is correct here. This is core BASICS of PLANT: once you know the definition or pathway step, Protoplast on cell wall is the clear fit. The wrong ones are A) Cell wall on protoplast; C) Vacuole on nucleus; D) Membrane on cytoplasm. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

BASICS of PLANT+PYQS

Hechtian strands are observed during:

That points to B: Plasmolysis. Compared with the other options, Plasmolysis is the one that correctly describes the BASICS of PLANT concept. The wrong ones are A) Cytokinesis; C) Cell elongation; D) Cell division. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
