Prompt Description

A high-resolution, high-detail black and white scanning electron microscopy image, presented as a scientific illustration, showing a close-up of the ultrastructure of a plasma cell. The image reveals highly dilated rough endoplasmic reticulum (RER). The RER forms numerous tightly packed, parallel stacks of lamellar cisternae. The cisternae are significantly expanded, and the membranes are densely studded with ribosomes.
