Brief description of cilia and flagella

1.	Brief description of cilia and flagella
Answer» Cilia moves fast and flagella moves slowly.Cilia have small hair-like structure and flagella have large hair-like structure. \tCilia and flagella are hair-like outgrowths of the cell membrane.\tCilia and flagella help in cell movement.\tCore of cilia and flagella is called the\xa0axoneme, possesses a number of microtubules running parallel to the long axis.\tThe axoneme usually has nine pairs of doublets of radially arranged peripheral microtubules, and a pair of centrally located microtubules. Such an arrangement of axonemal microtubules is referred to as the\xa09+2 array.\tThe central tubules are connected by bridges and is also enclosed by a central sheath, which is connected to one of the tubules of each peripheral doublets by a\xa0radial spoke\xa0and hence there are nine radial spokes.\tThe peripheral doublets are also interconnected by\xa0linkers.\tBoth the cilium and flagellum emerge from centriole-like structure called the\xa0basal bodies.
