Masses of rough endoplasmic reticulum also occur in some non-neuronal cells, where they are referred to as ergastoplasm, basophilic bodies, [1] or chromophilic substance. [4] While these organelles differ in some ways from Nissl bodies in neurons, [5] large amounts of rough endoplasmic reticulum are generally linked to the copious production of ...
The rough endoplasmic reticulum works in concert with the Golgi complex to target new proteins to their proper destinations. The second method of transport out of the endoplasmic reticulum involves areas called membrane contact sites, where the membranes of the endoplasmic reticulum and other organelles are held closely together, allowing the ...

Abundant rough endoplasmic reticulum combined with a well-developed Golgi apparatus makes plasma cells well-suited for secreting immunoglobulins. [4] Other organelles in a plasma cell include ribosomes, lysosomes, mitochondria, and the plasma membrane.
Rough (containing ribosomes) and smooth (without ribosomes) microsomes are made from the endoplasmic reticulum through cell disruption. These microsomes have an inside that is exactly the same as the endoplasmic reticulum lumen. Both forms of microsomes can be purified by a process known as equilibrium density centrifugation. Rough and smooth ...
These dyes intensely stain "Nissl bodies" (rough endoplasmic reticulum), which are abundant in neurons and reveal specific patterns of cytoarchitecture in the brain. Other common staining techniques used by histologists in other tissues (such as the hematoxylin and eosin or " H&E stain ") leave brain tissue appearing largely homogeneous and do ...
Diagram of the plant cell, with the cell wall in green. Cell walls serve similar purposes in those organisms that possess them. They may give cells rigidity and strength, offering protection against mechanical stress. The chemical composition and mechanical properties of the cell wall are linked with plant cell growth and morphogenesis. [11]
Synthesis of proteins is by the rough endoplasmic reticulum (RER), and both the rough and smooth endoplasmic reticulum (SER) are involved in secretion of the proteins formed. [citation needed] The endoplasmic reticulum (ER) is involved in conjugation of proteins to lipid and carbohydrate moieties synthesized by, or modified within, the hepatocytes.
