Quizplus · Accepted Answer

The structures labeled "4" in the figure are most likely cilia, as they are short, hair-like structures that cover the surface of certain cells, commonly used for movement or sensing the environment. Trichocysts are defensive organelles found in some protozoans, flagella are longer and usually fewer in number than cilia, pili are hair-like structures on bacteria used for attachment or conjugation, and pellicles are a layer of rigid proteins that support the cell membrane in some protozoans.
