a) cilia contain nice microtubule doublets surrounding a central pair of microtobules, while flagella contain only nine microtobule doublets.
b) cilia are composed of microfilaments and flagella are composed of intermediate filaments.
c) the protein filaments of cilia are "naked," while those of flagella are wrapped in an extension of the cell membrane.
d) cilia are typically more numerous and shorter than flagella
e) cilia are anchored only in the proteins of the cell membrane, while flagella are anchored in a special structure called the basal body.
