swelling of endoplasmic reticulum

Explanation:
Detailed explanation-1: -Intracellular polycationic molecules cause reversible swelling of the rough endoplasmic reticulum.
Detailed explanation-2: -Cellular swelling (synonyms: hydropic change, vacuolar degeneration, cellular edema) is an acute reversible change resulting as a response to nonlethal injuries.
Detailed explanation-3: -The endoplasmic reticulum is present only in eukaryotic cells. Prokaryotic cells like bacterial cells do not have the endoplasmic reticulum.
Detailed explanation-4: -Cell swelling occurs when the cell loses its ability to precisely control the influx of sodium (Na+) ions and water and efflux of potassium (K+) ions to the cytosol.
