Bound to their multitudinous cofactors they are actively engaged in "proteo-neo-genesis".
No, viruses do not have membrane bound organalles
There are two main types of ribosomes in cells: free ribosomes, which are found floating in the cytoplasm, and bound ribosomes, which are attached to the endoplasmic reticulum. Both types are responsible for protein synthesis within the cell.
Free ribosomes usually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported or included in the cell's membranes. Interestingly enough, free ribosomes and bound ribosomes are interchangeable and the cell can change their numbers according to metabolic needs.
Ribosomes are organelles within cells and are either bound or free. Organelles are structures inside the cells which perform specific functions. Bound ribosomes are attached to the organelle called the rough endoplasmic reticulum (rough because of the presence of the ribosomes) and there is also the smooth endoplasmic reticulum, without attached ribosomes. Ribosomes are protein producing "factories" and are abundant in cells actively involved in protein synthesis. Free ribosomes are scattered throughout the cell and the protein they produce is for usage within the cell. Much of the protein produced by the bound ribosomes is transported for use outside the cell.
Free ribosomes are found in the cytosol, which is the fluid portion of the cytoplasm, and are responsible for manufacturing proteins that will function as http://www.answers.com/topic/soluble proteins within the cytoplasm or form structural elements, including the cytoskeleton, that are found within the cytosol.
Prokaryotic organisms lack a true nucleus and membrane-bound organelles in their cells. They have a simple cell structure without internal compartments. Examples of prokaryotic organisms include bacteria and archaea.
Ribosomes are microscopic particles that are responsible for protein synthesis. Membrane-bound ribosomes are ribosomes that are attached to the rough endoplasmic reticulum of the cell.
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.

The difference between ribosomes of prokaryotes and eukaryotes is the structure of the ribosomes. Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. 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).
Bound ribosomes are found on the rough endoplasmic reticulum in a cell. Free ribosomes are found scattered throughout the cell.
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.
rer, ser, ribosomes, cytoskeleton
No, they are not. Neither prokaryotes like bacteria nor eukaryotes (like our cells) have membrane bound ribosomes.
Free ribosomes usually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported or included in the cell's membranes. Interestingly enough, free ribosomes and bound ribosomes are interchangeable and the cell can change their numbers according to metabolic needs.
