PSS- Sec-F-Transport

Water exchange between xylem and phloem occurs mainly at:

Go with C — Source and sink regions. Under PSS- Sec-F-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) Roots only; B) Leaves only; D) Stem nodes. When two options sound similar, choose the one that matches the textbook definition most tightly.

PSS- Sec-F-Transport

Casparian strip is impregnated mainly with

Answer: C) Suberin and lignin. 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) Cellulose; B) Pectin; D) Hemicellulose. Name the process first, then pick the option that describes it — don’t reverse cause and effect.

WATER TRANSPORT+PYQS

Major driving force for ascent of sap in tall plants is:

C fits best: Transpiration pull. Keep the WATER TRANSPORT basics straight and Transpiration pull stands out as the precise answer. Avoid: A) Root pressure; B) Capillary action; D) Diffusion. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
