ENDOPLASMIC RETICULUM

  • Endoplasmic reticulum is mesh like structure which are composed of numerous tube-like structures.
  • They extends from plasma membrane to nuclear membrane.
  • They are responsible to transmission of materials between the cell membrane and nuclear membrane.
  • They are absent in prokaryotic cells and matuared RBC’S of mammals.

There are two types of endoplasmic reticulum. They are:

(a)Rough Endoplasmic Reticulum(RER)

(b)Smooth Endoplasmic Reticulum(SER)

(a)ROUGH ENDOPLASMIC RETICULUM

  • The endoplasmic reticulum which have rough surface (due to the presence of ribosomes on its surface) is called rough endoplasmic reticulum.
  • They help in the formation of protein.

(b)SMOOTH ENDOPLASMIC RETICULUM

  • The endoplasmic reticulum which have smooth surface are known as smooth endoplasmic reticulum.
  • They help in the formation of lipids
  • They also responsible for the detoxification of the cell.

QUESTIONS FOR SELF EVALUATION

  1. ………………… is responsible for detoxification.
  2. ………………… endoplasmic reticulum help in the formation of proteins.
  3. ………………….endplasmic reticulum help in the formation of Lipids.
  4. Endoplasmic reticulum extend from ………………. to ………………….
