i) The Golgi complex is necessary for the transport of various bio molecules synthesized in the Endo-plasmic reticulum.
ii) Along with the function of transportation, the Golgi complex also aids in the conversion of many molecules like simple sugars into complex sugars.
iii) Lysosomes, which digest the unwanted materials in the cell are also synthesized by the Golgi complex.
iv) Thus, without the Golgi apparatus, the cell would not survive as there would be no conversion and transportation of bio-molecules and the cell would get infected by foreign particles as the lysosomes would not be functional.
