  3. Endoplasmic Reticulum The endoplasmic reticulum (ER) is a large network of membrane bound tubules, vesicles and sheets. The ER membrane is similar in structure to the plasma membrane. There are two types of ER-rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER)

  6. Rough Endoplasmic Reticulum RER looks rough under a microscope because it has particles called ribosomes attached to its surface. The ribosomes, which are present in all active cells, are the sites of protein manufacture. The manufactured proteins are then sent to various places in the cell depending on need, using the ER.

  7. Smooth Endoplasmic Reticulum The SER helps in the manufacture of fat molecules or lipids, important for cell function. Does not contain ribosome. Helps in detoxification of toxic and harmful substances.

  8. Membrane Biogenesis some proteins and lipids help in building the cell membrane some other function as enzymes or hormones.

  9. Functions ER serve as channels for the transport of materials between various regions of the cytoplasm or between the cytoplasm and the nucleus. The ER functions as a cytoplasmic framework providing a surface for some biochemical activities. SER plays a crucial role in detoxifying many poisons and drugs.
