$Cilia$ and $Flagella$ are hair-like outgrowths of the cell membrane. $Cilia$ are small structures which work like oars,causing the movement of either the cell or the surrounding fluid.

What is the number of microtubules in a centrosome?

Which of the following organelles is helpful in cell division?

$A$: The axoneme of a eukaryotic flagellum possesses a number of microtubules running parallel to the long axis.
$R$: It has a pair of peripheral doublet and a pair of centrally located microtubules.

Each centriole has a cartwheel organization having a whorl of tubulin fibrils at the periphery. These peripheral fibrils are composed of how many microtubules?

Study the following statements on cilium or flagellum and answer the question.
$(i)$ Cilium / Flagellum contains an outer ring of nine doublet microtubules surrounding two singlet microtubules.
$(ii)$ Cilia are smaller which work like oars,causing the movement of either the cells or surrounding fluid.
$(iii)$ Flagella are comparatively longer and responsible for cell movement.
$(iv)$ Cilium and flagellum are covered with plasma membrane. Which of the above statements are correct?
