Question

Quizplus · Accepted Answer

The endoplasmic reticulum (ER) is a network of membranes that crisscrosses the cytoplasm of eukaryotic cells. There are two types of the ER: the rough (RER), which has ribosomes attached to it, and the smooth (SER), which lacks ribosomes. Both types of ER are involved in the synthesis of lipids and proteins, as well as in the transport of molecules within the cell. The membranes of the ER provide channels for the movement of materials throughout the cytoplasm. The Golgi complex, mitochondria, and lysosomes also play important roles in intracellular transport and metabolism but are not primarily responsible for the network of membranes in the cytoplasm.
