Which organ is RER abundant?

Rough endoplasmic reticulum (RER), smooth endoplasmic reticulum (SER), and Golgi complex are abundant in mammalian hepatocytes (see Figs. 1-13 and 1-14).

Is RER in prokaryotic cells?

Rough endoplasmic reticulum, peroxisomes, and mitochondria are all bound by their own plasma membranes, and are only found in eukaryotic cells. Centrioles are a component of the cytoskeleton of eukaryotic cells, but are not found in prokaryotes.

Which cell contains a large rough endoplasmic reticulum and Golgi apparatus?

Where is it? Golgi apparatus is present in eucaryotic cells as one or more groups of flattened, membrane-bounded compartments or sacs. They are located very near the rough endoplasmic reticulum and hence near the nucleus.

Do plant cells have rough ER?

The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. Rough and smooth ER each manufacture different products for the cell.

What is RER in cell?

rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

Is DNA present in RER?

Endoplasmic reticulum do not contain any DNA they have only role in synthesizing protein via the translation process and and in Lipid production and detoxification of chemicals as they do not have any circular chromosome, As far as DNA is always found on chromosomes and mainly comprise gene which code for proteins.

Do prokaryotes have a centrosome?

Prokaryotes do not have centrioles. Centrioles make up the centrosome, which is important for organizing…

Do prokaryotes have cell membrane?

Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

What is RER made of?

What Is the RER? The rough endoplasmic reticulum (also called the RER), is an organelle found in both animal and plant cells. It is made up of interconnected, flattened membrane sacs. It’s also attached to the nuclear membrane, which contains the nucleus.
