Define E.R. and mention its types.
Answers
Answer: the endoplasmic reticulum or ER is a large network of membrane bound tubes and sheets it looks like long tube use around or oblong bags the endoplasmic reticulum membrane is similar in structure to the plasma membrane.
there are two type of endoplasmic reticulum rough endoplasmic reticulum and smooth endoplasmic reticulum.
rough endoplasmic reticulum bluekraft because it has ribosomes attached to its surface which are present in all active cells and their site of protein manufacture.
smooth endoplasmic reticulum helps in manufacture of fat molecules are lipids important for cell function.
I hope my answer will help you.
Answer:The endoplasmic reticulum (ER) is an important organelle in eukaryotic cells. It plays a major role in the production, processing, and transport of proteins and lipids. It is of two types- smooth E.R (SER) and rough E.R (RER)
RER
1) Rough endoplasmic reticulum has ribosomes attached to it giving the rough appearance.
2) Involved in protein synthesis.
SER
1) Smooth endoplasmic reticulum devoid of ribosomes.
2) Concerned with lipid synthesis.
