Explain the structure and function of the centrosome

An organelle present in animal cells that lie in the intracellular fluid called cytoplasm near the nucleus is known as centrosome. Plant and fungal cells lack centrosome. Centrosome plays a major role during cell division.

Structure- A daughter centriole and a mother centriole lie at an angle of 90 degrees to each other to form a centriole. The connection between these two centrioles is established by the interconnecting fibres. The centrioles in the centrosome are surrounded by an amorphous pericentriolar matrix. 

Functions- Centrosome performs many functions in the cell.

• It helps in the division of cell and also functions to maintain chromosome number when the cell is dividing. 
• It helps in microtubule organization during cell division.
• It also provides structure to the cell by regulating the changes in cellular shape.
