Final answer:
Cilia and flagella have a membrane that is continuous with the plasma membrane.
Step-by-step explanation:
True. Cilia and flagella are extensions of the plasma membrane. They are whip-like flagella or brush-like cilia that help cells move or perform specific functions. The flagella and cilia are made of axonemes, which are microtubules surrounded by cell membrane. So, the membrane of cilia and flagella is continuous with the plasma membrane.
