Matching labels to plant cell organelles

Steps:

• Identify the sap vacuole as the large central fluid-filled space in plant cells.
• Locate the nucleus as the spherical structure near the cell periphery, containing genetic material.
• Spot the chloroplast as the lens-shaped organelle with stacked thylakoids for photosynthesis.
• Assign labels based on diagram positions: X to vacuole, Z to nucleus, Y to chloroplast.

Why B is correct:

• Option B (X, Z, Y) precisely matches the standard positions: X for sap vacuole, Z for nucleus, Y for chloroplast, aligning with plant cell anatomy definitions.

Why the others are wrong:

• A misorders as vacuole-nucleus-chloroplast, swapping nucleus and chloroplast labels.
• C starts with Y (chloroplast) as vacuole, inverting the sequence incorrectly.
• D begins with Z (nucleus) as vacuole, mismatching all assignments.

Final answer: B
