♦ $\textbf{Centrosomes and Centrioles..}$

➡ Centrosome was discovered by $\textbf{Bendon.Boveri}$ named as centrosome.

➡ Centrosome is absent in almost all plant cell.

> Two centrioles (diplosome) located just outside the nucleus and lie at right angle (90°) to each other called Centrosome. or Microcentrum. each centriole is surrounded bg anorphous pericentriolar mass which is called as massules or crown or satellite.

♦ Centrioles are membraneless elongated structure which exhibit cart wheel structure (just like body of cilia). Basal body is also a type of centriole.

♦ Centriole mainly consist of 9 peripharal triplet fibres of tubulin.( 9 + 0 arrangement ).

♦ Centrioles are self duplicating units.

♦ Replication of centriole occur in s-phase.
