The Endoplasmic Reticulum Introduction. The endoplasmic reticulum or ER is a sub-cellular structure which performs several specialized tasks within the cell; hence it can be classified as an organelle. It is formed out of several interconnecting tubules and vesicles.The ER does not function in isolation, but coordinates with several other organelles.lide 1 of 4.

What is endoplasmic reticulum? The endoplasmic reticulum (ER) is an organelle that appears in all eukaryotic cells, usually surrounding the nucleus. The ER is made of a series of membranes that extend throu … ghout the jelly-like cytoplasm and kind of form a maze. The ER's main function is to manufacture and transport materials to other places.

- The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.

reticulum endoplasmic reticulum an ultramicroscopic organelle of nearly all higher plant and animal cells, consisting of a system of membrane-bound cavities in the cytoplasm, occurring in two types: granular or rough-surfaced, bearing large numbers of ribosomes on its outer surface, and agranular or smooth-surfaced.

Endoplasmic reticulum The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton. The phospholipid membrane encloses a space, the cisternal space (or lumen), which is continuous with the perinuclear space but separate from the cytosol.he smooth endoplasmic reticulum (abbreviated SER) has functions in several metabolic processes. It synthesizes lipids, phospholipids, and steroids. Cells which secrete these products, such as those in the testes, ovaries, and sebaceous glands have an abundance of smooth endoplasmic reticulum.
