Question

Endomembrane system are those group of cell organelles whose functions are co-ordinated such as ER, Golgi body etc. then why not Centrosome and centriole along with Nucleus(chromatin network) kept under this system as the spindle fibres produced by Centrosome and centriole during cell division passes through the kinetochore of chromosome which ultimately helps in division of cell?

Answer 1

because endomembrane system isnt about cell division,it deals with other functions,thats why those organelles aint included
