Who am I?

I support the cell, but I am not a cell wall. I have a body resembling a net.

Endoplasmic Reticulum

Endoplasmic Reticulum is one of the big organelle present inside the Cell. Found suspended in the cytoplasm, it starts from the nuclear envelope and ends almost closer to the Cell membrane. It occupies a major portion of cytoplasm thus it provides a framework that supports the cell and performs the major of the function of conduction of proteins. E. R has a net-like structure, interconnected by several foldings of its own fluid filled sheets and miniature tubes.
