The endoplasmic reticulum comes in two types: one has ribosomes on its surface, and the other doesn’t. The one without ribosomes is called smooth endoplasmic reticulum, and the one with ribosomes is called rough endoplasmic reticulum. These membranes fold continuously and connect to the outer layer of the nucleus. Apart from sperm cells and red blood cells, the endoplasmic reticulum is found in all other kinds of eukaryotic cells.
The Golgi apparatus, also known as the Golgi complex or Golgi body, got its name from scientist Camillo Golgi who discovered it. It’s found in all types of eukaryotic cells, including those in plants and animals. This organelle is surrounded by a membrane and located in the cytosol of the cell. Let’s learn more about the Golgi complex.
