What is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?

The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.

Can rough endoplasmic reticulum be seen under an electron microscope?

The rough endoplasmic reticulum (RER) is so named because the ribosomes attached to its cytoplasmic surface give it a studded appearance when viewed through an electron microscope.

What is a micrograph of a cell?

A micrograph is a photo or digital image taken through a microscope to show a magnified image of a specimen. While organelles have identifying structures, specific shapes may vary depending on the location of cross-sections. Prokaryotic Cell Features.

What are the functions of SER and RER?

Proteins synthesized by the RER have specific final destinations, such as the cell membrane, cell exterior, or the ER itself. SER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane.

Which of the following functional differences between the rough and smooth endoplasmic reticulum is explained by the structural differences between them?

Which of the following functional differences between the rough and smooth endoplasmic reticulum (ER) is explained by the structural differences between them? Rough ERER can synthesize and package proteins for export, and smooth ERER cannot.

Is smooth ER visible under light microscope?

Recognize cell organelles, which are visible by regular light microscopy (Nucleus, nucleolus, basophilic rough endoplasmic reticulum, secretory vesicles) and by EM (Golgi complex, lysosomes, rough and smooth ER and others).

What organelles can be seen with an electron microscope?

The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph. (Courtesy of Brian Gunning.) (more…)

How do you describe a micrograph?

A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times.
