ORGANELLE DIAGRAM: SMOOTH ENDOPLASMIC RETICULUM:
In this picture, the smooth endoplasmic reticulum is seen as a tangle of pink interconnected tubules. Unlike the rough ER, it lacks ribosomes.
The smooth ER is continuous with the rough ER but has different functions.
- name(s): smooth endoplasmic reticulum, smooth ER, tubular endoplasmic reticulum, agranular endoplasmic reticulum
- location: in cytoplasm
- appearance: interconnected and ramifying tubules; no ribosomes
- size: tubules are about 150nm in diameter (variable)
- function: used in lipid synthesis, detoxification and other metabolic processes.
