What is the function of the endoplasmic reticulum in plant and animal cells?

The organelle called ‘endoplasmic reticulum’ occurs in both plants and animals and is a very important manufacturing site for lipids (fats) and many proteins. Many of these products are made for and exported to other organelles.

What is the main function of the endoplasmic reticulum in an animal cell quizlet?

endoplasmic reticulum- A system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.

What is the role of endoplasmic reticulum in a plant cell?

The endoplasmic reticulum (ER) is the port of entry of proteins into the endomembrane system, and it is also involved in lipid biosynthesis and storage. This compartment is involved in cell to cell communication via the plasmodesmata, and, in specialized cells, it serves as a storage site for proteins.

What does rough ER do in a cell quizlet?

Function: Rough endoplasmic reticula are involved in the synthesis of proteins.

Do animal cells have a endoplasmic reticulum?

The endoplasmic reticulum (ER) in animal cells is an extensive, morphologically continuous network of membrane tubules and flattened cisternae. Many of these functions are not homogeneously distributed throughout the ER but rather are confined to distinct ER subregions or domains.

What is endoplasmic reticulum structure and function?

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.

How does endoplasmic reticulum modify proteins?

Inside the ER, the proteins fold and undergo modifications, such as the addition of carbohydrate side chains. These modified proteins will be incorporated into cellular membranes—the membrane of the ER or those of other organelles—or secreted from the cell. Micrograph and diagram of the endoplasmic reticulum.

Which of the following cellular functions is performed by endoplasmic reticulum?

The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].

What is the function of the RER rough endoplasmic reticulum?

rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What is the function of the smooth endoplasmic reticulum in a human cell?

The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.
