Endoplasmic Reticulum is a series of long, tube-like/membraneous structure. They consist of Rough (with ribosomes) and Smooth (without ribosomes), and they are mostly composed of lipids.
Their main purpose is to transport substances throughout the cell, including, but not limited to, amino acids formed in rRNA, and other complex molecules.
They and the Golgi are responsible, basically, for the overall "transportation network" of the cell.
Also, in liver/muscle cells, they have specific functions relating to Calcium.

Begging for help by adding zz is stupid. Do your own homework and quit wasting the time of adults - YA is not a place for teenie boppers.

Its where lipid components of the cell membrane are assembled, along with protiens and other materials that are exported from the cell.
