Turgor changes in xerophytic leaf cells under conditions P and Q

Steps:

• Xerophytic leaves minimize water loss; layer Y likely epidermis or mesophyll affected by osmosis.
• Condition P allows water uptake (e.g., humid), leading to turgid cells; Q causes water loss (e.g., dry), leading to plasmolysis.
• Statement 1 correct: turgid (high pressure) in P, plasmolysed (cell membrane pulls from wall) in Q.
• Statement 3 correct: lower turgor in Q due to dehydration vs. P.
• Statements 2 and 4 ambiguous without diagram details.

Not enough information to confirm statement 4 or rule out contradictions in options including 2.

Final answer: Not enough information.
