The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.

What is the difference in the rough ER and the smooth ER and what is the function of each?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
What is smooth ER do?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. ... The smooth endoplasmic reticulum also carries out the metabolism of carbohydrates and steroids.
What is the similarities between rough and smooth endoplasmic reticulum?
Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.
Why is the rough ER important?
The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Rough ER is the organelle that reads the DNA instructions to make the proteins. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus.
What is smooth endoplasmic reticulum Class 9?
The smooth endoplasmic reticulum has a tubular form. It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism. Smooth ER transports the products of the rough ER to other cellular organelles, especially the Golgi apparatus.
What is the role of SER?
Answer: The endoplasmic reticulum (ER) is a network of membranes that is present inside eukaryotic cells. These structures are responsible for the production and transportation of proteins, fats and other essential molecules required for the functioning of a cell.
What is the difference between smooth and rough surface?
is that rough is having a texture that has much friction not smooth; uneven while smooth is having a texture that lacks friction not rough.
What would happen without the smooth ER?
It plays an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well and the smooth ER was damaged, the cell would no longer be able to produce ribosomes which are needed to make proteins.
How does the smooth ER make lipids?
The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes. ... In the reproductive organs, smooth ER in the cells produces the steroid hormones testosterone and estrogen.
What happens if the smooth ER malfunctions?
A malfunction of the ER stress response caused by aging, genetic mutations, or environmental factors can result in various diseases such as diabetes, inflammation, and neurodegenerative disorders including Alzheimer's disease, Parkinson's disease, and bipolar disorder, which are collectively known as 'conformational ...
Why is RER Class 9 rough?
Rough Endoplasmic Reticulum (RER) appears rough because of the presence of ribosomes on it. Ribosomes are sites for biological protein synthesis. ... Polyribosomes are aggregation of several ribosomes held together by a string of mRNA.
How is rough er different from smooth ER What functions do they perform in a cell class 9?
Rough ER is different from smooth ER in having ribosomes (protein units ) on its surface. ... The Ribosomes present in RER are the structures responsible for making proteins which are further sent to the lumen . It is also responsible for making phospholipids which make up the membranes of cells. Hope that helps !
