Question

write the three morphological forms of endoplasmic reticulum ? Give two difference between SER andRER​

Answer 1

Answer:

ER is classified into two distinct SER &RER

SER is known as smooth endoplasmic reticulum. SER has ribosomes.

RER is known as rough endoplasmic reticulum.

RER don't have ribosomes.

Answer 2

Answer:

The three forms of Endoplasmic reticulum are cisternae, vesicles, and tubules.

Smooth Endoplasmic reticulum (SER):-

i) It does not have ribosomes attached to its surface.

ii) It plays role in calcium storage of the muscle cells.

Rough Endoplasmic Reticulum(RER):-

i)It does have ribosomes attached to its surface.

ii) It helps in protein synthesis inside the cell.

Explanation:

The Endoplasmic Reticulum plays role in the protein synthesis and also the transportation system of the cell.

It consists of two regions:- SER(Smooth Endoplasmic reticulum) and RER(Rough endoplasmic reticulum).

It also exists in three forms that are cisternae, vesicles, and tubules.
