It is connected to a membrane called the Nucleus
it is connected to the nuclear membrane and the smooth ER
smooth ER
The Rough Endoplasmic Reticulum is connected to the nuclear membrane and is continuous with the Smooth Endoplasmic Reticulum within the cell. Its distinctive rough appearance is due to the presence of ribosomes on its surface, which are involved in protein synthesis.
They're seperate organelles, but they are connected by a membrane separating the two.
The rough endoplasmic reticulum (RER) is connected to the nuclear envelope, which is a double membrane surrounding the nucleus of a eukaryotic cell. Ribosomes attached to the RER play a crucial role in protein synthesis and modification.
The rough Endoplasmic Reticulum is a continuation from the nuclear membrane, which in turn is connected to the smooth ER.
The rough endoplasmic reticulum is connected to the nuclear envelope membrane in eukaryotic cells. This connection allows for the transport of proteins synthesized on the ribosomes of the rough ER to other parts of the cell.
Endoplasmic reticulum
it is cytoplasm
The rough ER appears rough due to the presence of ribosomes on the membrane surface.
Rough ER
No, they do not. Prokaryotic cells have no membrane-bound organelles such as rough endoplasmic reticulum. The 70s ribosomes found in prokaryotic cells are therefore free in the cytoplasm as opposed to attached to the rough endoplasmic reticulum.
