Yes, the ER or endoplasmic reticulum is a membrane-bound organelle.
What else can I help you with?
Is the smooth ER membrane bound?
Yes, the smooth endoplasmic reticulum (ER) is membrane-bound. It lacks ribosomes on its surface, giving it a smooth appearance compared to the rough ER, which has ribosomes attached. The smooth ER plays a role in lipid metabolism and detoxification processes within the cell.
Do bacterial cells have and ER?
No, bacterial cells do not have an endoplasmic reticulum (ER). The ER is a membrane-bound organelle found in eukaryotic cells, involved in protein and lipid synthesis. Bacteria, being prokaryotes, lack membrane-bound organelles, and their cellular processes occur in the cytoplasm or at the cell membrane.
Is ER membrane bound organelle?
Yes, the endoplasmic reticulum (ER) is a membrane-bound organelle in eukaryotic cells. It plays a key role in protein synthesis, lipid metabolism, and detoxification reactions within the cell. The ER is interconnected with the nuclear envelope and consists of two main regions: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER).
What is a membrane bound sac formed from smooth ER?
A membrane-bound sac formed from smooth ER is called a vesicle. It plays a role in transporting proteins and lipids within the cell, as well as facilitating communication between different organelles.
Do prokaryotes have rough er?
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.
How are organelles in procaryotic cells different from organelles in eukaryotic cells?
prokaryotes: no membrane-bound organelles (no nucleus for instance) eukaryotes: membrane-bound organelles (such as nucleus, ER, Golgi apparatus etc.)
Do bacteria have ER?
No, bacteria do not have endoplasmic reticulum (ER) like eukaryotic cells. Bacteria lack membrane-bound organelles, including the ER, and instead have a simpler internal structure.
Which organelle makes new plasma membrane as it packages items for export?
Both the ER and the Golgi App make the membrane bound transport vescivles.
What is the cellular structure that produces carbohydrates and lipids?
The endoplasmic reticulum (ER) is the cellular structure responsible for producing both carbohydrates and lipids. The smooth ER is involved in lipid synthesis, while the rough ER is involved in synthesizing membrane-bound proteins and modifying proteins.
Do eukaryotic cells have membrane-bound organelles?
Eukaryotes contain membrane bound organelles. Prokaryotes do not contain membrane bound organelles. However, prokaryotes do contain ribosomes which is an example of a non-membrane bound organelle.
Where is the lysosome located?

Do yeast have membrane bound organelles?
Yeast do not have membrane bound organelles.
