Short, hairlike structures used only by eukaryotic cells for movement are called:

• A. Pili
• B. Fimbriae
• C. Flagella
• D. Cilia

Answer: (D)

Verified step by step guidance

1. Understand the types of cell surface structures involved in movement and attachment in eukaryotic and prokaryotic cells.
2. Recall that pili and fimbriae are primarily found in prokaryotic cells and are used mainly for attachment rather than movement.
3. Recognize that flagella are long, whip-like structures used by both prokaryotic and eukaryotic cells for movement, but they are typically longer and fewer in number.
4. Identify that cilia are short, hairlike structures found only in eukaryotic cells and are used specifically for movement or to move substances along the cell surface.
5. Conclude that the correct term for short, hairlike structures used only by eukaryotic cells for movement is 'cilia'.
