Correct Answer
Detailed Explanation
The cilia and flagella are enclosed by a unit membrane which is an extension of the plasma membrane of the cell. The axoneme is generally connected to the surrounding plasma membrane by filaments called membrane links. It consists of a doublet arranged in the periphery which is joined to one another by interdoublet links. From each subunit of doublet, a radial spoke arises near the central sheath.
