No,they are not covered.They are also in prokariyotes.
No, they are not. Neither prokaryotes like bacteria nor eukaryotes (like our cells) have membrane bound ribosomes.
They are not covered by a membrane.
In a typical animal cell, the only major organelles not covered by membranes are the ribosomes. Ribosomes are composed of r-RNA and proteins.
Scientifically explaining, they are membrane-covered organelles that are found only in the eukaryotic cell. Prokaryotic cells do not have membrane-covered organelles. The only organelle they have, not membrane-covered, are ribosomes.
im sorry i would try to help you but im looking for the same answer right now 2! stupid science hw!
Ribosomes have no membrane as they are organelles; they are inside / parts of the cell.
As a general rule, practically all the internal organelles of a cell are covered by a protective membrane, except for one type, which couldn't even be called a real organelle, and those are the Ribosomes. More a macromolecular assemble than a cell organelle, the reason because they aren't membrane-bound is because they can directly interact with the membrane in order to exchange proteins, so, having their own membrane would actually act as a barrier for them to do their job correctly.
The ribosome is an organelle that is not surrounded by a membrane.
That's correct! Ribosomes on the rough endoplasmic reticulum (ER) are responsible for protein synthesis. The rough ER is involved in the synthesis and processing of proteins that are ultimately exported from the cell or used in the cell membrane.
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
The rough endoplasmic reticulum is covered in ribosomes. Together, they make proteins for inside the cell and for other cells.Rough ER is covered with ribosomes.
