What is endoplasmic reticulum explain its types and functions?

The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.

What is endoplasmic reticulum and its types Class 9?

Class 9 Biology Fundamental Unit of Life. Endoplasmic reticulum. Endoplasmic reticulum. The large network of membranous sheets and tubes is called endoplasmic reticulum. They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell.

What are the 5 functions of 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 are the functions of the two types of ER?

The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. Differences in certain physical and functional characteristics distinguish the two types of ER, known as rough ER (RER) and smooth ER (SER).

What is the function of endoplasmic reticulum ER Class 9?

Endoplasmic reticulum performs the following functions: It is responsible for the production and secretion of steroid hormones. It is also responsible for the synthesis of essential lipids such as phospholipids and cholesterol. It is responsible for the metabolism of carbohydrates.

What is function of Ser Class 9?

The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.

What is the function of the endoplasmic reticulum Toppr?

Functions of Endoplasmic Reticulum Endoplasmic reticulum function includes the Golgi apparatus, lysosomes, plasma membrane, etc. In addition, it is responsible for transport. Transport of carbohydrates and proteins to another organelle.

What is endoplasmic reticulum for class 8th?

Answer: Rough endoplasmic reticulum is an organelle found in eukaryotic cells. It’s main function is to produce proteins. These proteins help in building cell membrane.

What is the function of endoplasmic reticulum Class 9?

What is the function of smooth endoplasmic reticulum?

smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …

What is the function of endoplasmic reticulum for class 11th?

What is the function of endoplasmic reticulum Class 8?

What are diseases caused by endoplasmic reticulum?

Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease, multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases, and familial encephalopathy with neuroserpin inclusion bodies.

What does the endoplasmic reticulum do in a plant cell?

In plant cell, the endoplasmic reticulum acts as a port for the entry of proteins into the membrane. It also plays a vital role in the biosynthesis and storage of lipids . There are number of soluble membrane, which are associated with the enzymes and the molecular chaperones.

What is the function of endoplasmic rectum?

See Article History. Alternative Title: ER. Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .

What does the Golgi vessicles do in the endoplasmic reticulum?

The Golgi apparatus is responsible for transporting, modifying , and packaging proteins and lipids into vesicles for delivery to targeted destinations. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds.
