Free ribosomes.

ribosomes
The 'free' ribosomes are for local use within the cell, whereas the ribosomes attached to the ER are transported to other parts of the cell or transported away from the cell.
It is called the cytosol
Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.
In eukaryotic cells, they are formed most often in the nucleolus. In eukaryotes, the ribosomes may be classified as either 'free' or 'bound'. Free ribosomes may be found suspended in the cytosol whereas bound ribosomes are attached to endoplasmic reticulum (as such called rough endoplasmic reticulum). Free ribosomes are involved in the synthesis of proteins that will function in the cytosol while bound ribosomes in the synthesis of proteins that are to be exported or used within the cell membrane. The two types of ribosomes have similar function and structure, and in fact, are interchangeable.
Free ribosomes.
We call these unattached ribosomes free ribosomes as they are not attached to a membrane.
There are two places that ribosomes usually exist in the cell: suspended in the cytosol and bound to the endoplasmic reticulum. These ribosomes are called free ribosomes and bound ribosomes respectively.
Fixed ribosomes are attached to the endoplasmic reticulum. The ribosomes are organelles that are suspended in the cytosol which is bound to the endoplasmic reticulum.
Free Ribosomes make proteins that funciton within the the Cytosol.
ribosomes
Proteins are translated from mRNA in ribosomes. They can either be free-floating ribosomes in the cytosol, or attached ribosomes on the rough ER.
Ribosomes
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.
There are two places that ribosomes usually exist in the cell: suspended in the cytosol and bound to theendoplasmic reticulum. These ribosomes are called free ribosomes and bound ribosomes respectively. In both cases, the ribosomes usually form aggregates called polysomes.
The 'free' ribosomes are for local use within the cell, whereas the ribosomes attached to the ER are transported to other parts of the cell or transported away from the cell.
Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.
