ER (endoplasmic reticulae) are the pathways in the cytoplasm of the cell connecting the nucleus. Smooth ER are without ribosomes on its membrane and rough ER have several ribosomes lining up the membrane. The ribosomes help in the assembly of amenoacids to form the proteins as per message received from mRNA.
what structure is found on the rough er that is noyt found on the smooth er
Ribosomes
rough- ribosomes attached smooth- no ribosomes
The smooth endoplasmic reticulum and the rough endoplasmic reticulum.
Ribosomes
The basic difference between the rough endoplasmic reticulum and the smooth endoplasmic reticulum is the rough ER has ribosomes latched on to it. This is what makes it "rough" and since the smooth ER does not have these organelles on it, it is smooth.The RER and the SER also differ in function. The rough ER is the cell's "membrane factory." Proteins and phospholipids that form part of all cellular membranes are manufactured in the rough ER. The smooth ER's main functions are lipid metabolism and synthesis of cholesterol.
Ribosomes are found on the rough ER, which are responsible for protein synthesis. Smooth ER does not have ribosomes.
Smooth and rough!
Satin has a smooth texture due to its weave structure, which creates a glossy finish on the fabric.
Noopppppppppppeeeeeeeere
Similar but different. The function of the endoplasmic reticulum can vary greatly with cell type, and even within the same cell it can have different functions depending on whether it is rough or smooth.
