Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's.

When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their destinations.

Ribosome in eukaryotes are called 80S ribosomes and consist of a small 40S subunit and a larger 60S subunit.

Prokaryotes have 70S ribosomes consisting of a 30S and 50S subunits.

Hope this helps.

Do animals belong to Prokaryotes?

No, animals do not belong to prokaryotes. Animals are eukaryotic organisms, meaning they have cells with a distinct nucleus and other membrane-bound organelles. Prokaryotes, on the other hand, are single-celled organisms that lack a nucleus and other membrane-bound organelles.


What 3 things does the nucleus contain?

The nucleus contains chromosomes, which carry genetic information in the form of DNA. It also contains the nucleolus, which is involved in the production of ribosomes. Additionally, the nucleus is surrounded by a nuclear membrane to separate its contents from the rest of the cell.


What is one eukaryotic organism?

Eukaryotes are organisms with a "true" nucleus and membrane-bound organelles. This means that their DNA is covered by a phospholipid membrane and contains various organelles made of same materials. In that sense, many things are considered eukaryotic. Mammals, birds, reptiles, amphibians, fish, plants, and even protists are all eukaryotes.


What is a bacteria organelle?

Bacteria do not have organelles like eukaryotic cells do. Instead, they have specialized regions within the cell that perform specific functions, but these are not considered organelles. Examples include the nucleoid region where the DNA is located, ribosomes for protein synthesis, and cell membrane for transport and signaling.


Is protein synthesis a function of cell membrane?

No, protein synthesis is not a function of the cell membrane. Protein synthesis occurs in the ribosomes of the cell, which are located in the cytoplasm or on the rough endoplasmic reticulum. The cell membrane is mainly involved in regulating the movement of substances in and out of the cell.

Where are cell organelles in the cell?

The organelles of a cell are scattered around everywhere in the cell membrane. They are all inside. Some organelles may have a special position based on their job. For example, Golgi bodies, which package and send out waste, are located near the cell membrane so it can move things through the semi-permiable membrane.

What do organelle do not have?

There are so many different types of organelles. This therefore means that the organelles do not have various things depending on the particular type. Most organelles do not have a double membrane.
