Hint: The cell also needs the structural framework just like the body of the organism. The organelle present in the cell helps it in providing the necessary structure. It also helps in transferring the signals from one cell to the other.
Complete answer:
The endoplasmic reticulum is the cell organelle which serves major functions like providing the mechanical support, enzyme regulation, protein synthesis, and the detoxification of the drug. ER is considered as the major site for the production of the proteins. This is done with the help of ribosomes present on the surface of the ER. This type of endoplasmic reticulum is known as the rough endoplasmic reticulum or RER. The smooth endoplasmic reticulum is the one which is devoid of the ribosomes. SER helps in the detoxification of the chemicals which enter the cell. SER also helps in the synthesis of carbohydrates and vitamins. It is also used in making lipids for the cell. ER generally functions as the cytoskeleton of the cell and provides it with the mechanical support to the colloidal cytoplasmic matrix. The rough endoplasmic reticulum is more abundant than the smooth endoplasmic reticulum. The SER helps in the detoxification of the chemicals present in the liver cells.
So, the correct answer is ‘ER’.
Note: The structural framework of the cell is provided by the ER or the endoplasmic reticulum. The rough endoplasmic reticulum is more abundant than the smooth endoplasmic reticulum. The RER is the main site for the protein synthesis whereas the SER is the main site for the lipid synthesis.
