Final answer:
Yes, eukaryotic cells can have a cell wall and a flagellum.
Step-by-step explanation:
Yes, eukaryotic cells can have a cell wall and a flagellum. The cell wall is a rigid outer layer that provides structural support and protection to the cell. While most eukaryotic cells do not have a cell wall, some do, such as plant cells and fungal cells. The flagellum, on the other hand, is a whip-like structure that helps with cell movement. While eukaryotic flagella are structurally distinct from prokaryotic flagella, eukaryotic cells can have flagella for locomotion. The eukaryotic flagellum is composed of microtubules and uses dynein motor proteins to bend and move.
