Final answer:
Plasma cells indeed have abundant RER and a well-developed Golgi apparatus to produce and process large quantities of antibodies for the immune system.
Step-by-step explanation:
It is true that plasma cells have abundant Rough Endoplasmic Reticulum (RER) and a well-developed Golgi apparatus. Plasma cells are specialized white blood cells that produce antibodies. The RER is studded with ribosomes, which makes it rough and is where proteins are synthesized. These proteins, primarily antibodies in plasma cells, are then transported to the Golgi apparatus. The Golgi apparatus functions in sorting, tagging, packaging, and distributing these proteins. The RER is also responsible for the synthesis of phospholipids that are important for cell membranes.
The extensive network of the RER in plasma cells allows for the efficient production of large amounts of proteins required for the immune response. Similarly, the well-developed Golgi apparatus in plasma cells is essential for processing and preparing the antibodies for secretion out of the cell. This cellular machinery is vital for the plasma cell's function in the immune system.
