The Correct solution is Centriole.

  • In eukaryotic cells, the centrosome is the main microtubule-organizing centre (MTOC), consisting of two centrioles surrounded by an electron-dense matrix called the pericentriolar material (PCM).
  • Centrioles are the  two cylindrical structures that make up the centrosome.
  • Each is organised in a cartwheel pattern.
  • A centriole is made up of a ring of microtubule triplets.
  • The triplets next to each other are linked.
  • The core section of a centriole has a proteinaceous hub.
  • The triplets are connected to the hub via radial spokes.
  • During cell division, these centrioles aid in the organisation of the spindle fibres and astral rays.
  • They also serve as the foundation for cilia and flagella.
  • The duplication of centrioles ensures that each daughter cell receives two centrioles.
  • The centrosome in multicellular species' cells is derived from the basal body in unicellular organisms' cells.
