Identifying Xylem in Plant Tissues

Steps:

• Recall xylem as the primary tissue for water transport in plants.
• Analyze choices as patterns marking tissue positions in a stem cross-section diagram.
• Match ✓ symbols to xylem locations (e.g., positions 2 and 5 in a typical dicot stem).
• Select the option with ✓ only on xylem, excluding phloem or ground tissues.

Why B is correct:

• Xylem conducts water via tracheids and vessels, as defined in plant anatomy.

Why the others are wrong:

• A marks only one position, missing multiple xylem strands.
• C includes an extra ✓ on phloem, which transports sugars.
• D marks parenchyma instead of xylem.

Final answer: B
