PSS- Sec-F-Transport

During plasmolysis, which structure retracts from the cell wall?

Correct option is C, Protoplast. In PSS- Sec-F-Transport problems like this, the accurate statement is Protoplast; the others are common mix-ups. Not these: A) Cell wall; B) Tonoplast; D) Middle lamella. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

WATER POTENTIAL+PYQS

Higher solute concentration inside cell causes:

That points to C: Water inflow and turgor. Compared with the other options, Water inflow and turgor is the one that correctly describes the WATER POTENTIAL concept. The wrong ones are A) Water to move out; B) Decrease in Ψp; D) Cell death. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

BASICS of PLANT+PYQS

Plasmolysis occurs when plant cell is placed in:

C fits best: Hypertonic solution. Keep the BASICS of PLANT basics straight and Hypertonic solution stands out as the precise answer. Avoid: A) Hypotonic solution; B) Isotonic solution; D) Pure water. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

BASICS of PLANT+PYQS

Tonicity of a solution refers to its ability to:

Go with B — Modify cell volume. Under BASICS of PLANT, 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) Change temperature; C) Break cell wall; D) Alter metabolism. When two options sound similar, choose the one that matches the textbook definition most tightly.

BASICS of PLANT+PYQS

Osmotic pressure is usually measured in units of:

Atmosphere or bar (C) is correct here. This is core BASICS of PLANT: once you know the definition or pathway step, Atmosphere or bar is the clear fit. The wrong ones are A) Kelvin; B) Joule; D) Watt. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
