5. Organelles of Vesicular Trafficking System: The main function of these organelles is to manage the distribution of material (food particles or proteins) throughout the cell. 3 different organelles such as endoplasmic reticulum, Golgi apparatus and lysosome, co-ordinately work together to maintains vesicular transport of material across the cell (Figure 4.3). Eukaryotic cell takes up the solid material from outside through a process called “ endocytosis ” whereas uptake of liquid is through a process called as “ pinocytosis ”. Similarly material is secreted out of the cells through “ exocytosis ”. In addition, intravesicular system delivers protein synthesized in endoplasmic reticulum to different organelles.
