No, prokaryotes do not possess an endoplasmic reticulum.
Prokaryotes do not have membrane-bound organelles found in eukaryotic cells, such as a nucleus, mitochondria, endoplasmic reticulum, or Golgi apparatus. Additionally, prokaryotes lack membrane-bound compartments like the endomembrane system seen in eukaryotic cells.
If the bacteria has eukaryotic cells, then yes, since without the membrane the cells can be destroyed and invaded. I write this assuming you know mostly what I'm talking about, I can detail this more if you want. No membrane = no protection = no cell
The plural form of endoplasmic reticulum is endoplasmic reticula.
Rough endoplasmic reticulum
Just like that.
The endoplasmic reticulum does not possess organelles, but it has got ribosomes attached to it , which helps in protein synthesis.
In eukaryotes, it surrounds the nucleus. Prokaryotes don't have them.
No, viruses do not have their own endoplasmic reticulum. They rely on host cells to carry out their replication and do not possess the cellular machinery needed to produce their own endoplasmic reticulum.
No endoplasmic reticulum and no Golgi apparatus.
Smooth endoplasmic reticulum is a eukaryotic organelle found in eukaryotic cells, which includes all plant and animal cells. Prokaryotic cells, such as bacteria, lack membrane-bound organelles like the endoplasmic reticulum.
Prokaryotic cells lack a nucleus and membrane bound organelles. Therefore only Eukaryotic cells possess the endoplasmic reticulum.
Prokaryotes do not have membrane-bound organelles found in eukaryotic cells, such as a nucleus, mitochondria, endoplasmic reticulum, or Golgi apparatus. Additionally, prokaryotes lack membrane-bound compartments like the endomembrane system seen in eukaryotic cells.
they don't have organelles, since the cytoplasm does the metabolic work, and technically we will only find the circular DNA in the nucleoid region and some ribosomes (which are NOT organelles, 'cause an organelle is a cellular structure that is protected by a membrane, like mitochondria, chloroplasts) in a prokaryotic cytoplasm.
Eukaryotic cells have two types of endoplasmic reticulum: Smooth ER (SER); Rough ER (RER).
Ribosomes can be found as free ribosomes in the cytosol and also on the rough endoplasmic reticulum. Both are involved in protein synthesis. In cells that are prokaryotes, like bacteria, they are only found free.
is the endoplasmic reticulum an Eukaryotic cell?
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.
