Explanation: 

Detailed explanation-1: -The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

Detailed explanation-2: -Secretory proteins, most of which are glycoproteins, are transported through the endoplasmic reticulum membrane. One of the functions of the ER is to act as a channel for material transport between different regions of the cytoplasm or between the cytoplasm and the nucleus.

Detailed explanation-3: -Transporting channels of the cell is Endoplasmic reticulum.

Detailed explanation-4: -The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton.
