The endoplasmic reticulum essentially aids in cellular homeostasis by providing the main transport mechanism for proteins within the cell.
Explanation:
Since the endoplasmic reticulum is a membrane-like structure that form channels within the cytoplasm of the cell, it helps in the transportation of materials such as synthesized proteins within the cytoplasm. Hence, helping to achieve a stable internal environment by the action of the transported proteins such as hormones , enzymes etc act on their target areas.
