    Q & A on Components of Cytoplasm

    Which organelle divides and compartmentalizes the cell?  The endomembrane system, which fills the cell and divides it into compartments, and is visible only through electron microscopy. The endoplasmic reticulum (ER), a series of interconnected membranous tubes and channels in the cytoplasm, is the largest and most extensive system of the internal membranes. What is the function of the endomembrane system? The endomembrane system allows macromolecules to diffuse or be transferred from one of the components of the system to another. What is the difference between rough and smooth endoplasmic reticulum? Rough endoplasmic reticulum are regions rich in ribosomes that manufacture proteins. These regions appear to have a pebbly surface that is somewhat similar to sand-paper.…
