When looking at the endoplasmic reticulum of a cell, the microscope zooms in enough to see ribosomes that are embedded in the outside of the endoplasmic reticulum. Which type of endoplasmic reticulum is this?
A. Bumpy
B. Smooth
C. Solid
D. Rough
Answer (2)
The type of endoplasmic reticulum with ribosomes embedded in its surface is called Rough endoplasmic reticulum (RER). The presence of these ribosomes gives the RER its characteristic bumpy appearance. In contrast, smooth endoplasmic reticulum (SER) does not have ribosomes and serves different functions in the cell. ;
The type of endoplasmic reticulum with ribosomes embedded on its surface is known as the Rough endoplasmic reticulum (RER). The ribosomes give it a bumpy appearance and are essential for protein synthesis. Therefore, the correct answer is D. Rough.
