Root Hairs: Functions and Characteristics Steps:

• Identify key functions of root hairs from biology: they increase surface area for absorption, are extensions of epidermal cells, and aid in water/mineral uptake.
• Evaluate statements 1, 2, 3 against these functions (assuming standard textbook claims: 1=increase absorption area, 2=epidermal extensions, 3=found in zone of maturation).
• Cross-check which combination matches all three as correct.
• Select option covering 1, 2, and 3.

Not enough information: Statements 1, 2, and 3 are not provided.

Final answer: Not enough information.
