Matching specialized cell features to diagrams

Steps:

• Identify specialized features: 1 as root hair for absorption, 2 as nerve cell for transmission, 3 as red blood cell for transport.
• Match to diagram labels: J shows elongated projection (root hair), K shows branched extensions (nerve), L shows biconcave disc (red blood), M shows thick walls (xylem).
• Compare choices: Eliminate mismatches in A, B, D.
• Select C as it aligns 1-L (biconcave), 2-K (nerve), 3-M (xylem).

Why C is correct:

• C matches root hair to L (absorption via surface area), nerve to K (impulse conduction via dendrites), red blood to M (oxygen transport via hemoglobin), per cell specialization definitions in biology.

Why the others are wrong:

• A mismatches 1 to J (xylem, not absorption) and 3 to K (nerve, not transport).
• B mismatches 1 to K (nerve, not root) and 3 to L (red blood, not xylem).
• D mismatches 1 to M (xylem, not root) and 2 to L (red blood, not nerve).

Final answer: C
