There are many systems within the cell that have to come together and function exactly right in order for protein synthesis to occur.
For starters, the cell's DNA serves as the template for proteins. One gene corresponds to the information needed to produce one type of protein.
Cells will first copy a single gene to an intermediate form that the protein generating machinery can read from. This template is just a modified form of DNA and is called mRNA. It hangs out in the cytoplasm waiting for protein generating machinery to come by and read it.
The protein generating machinery, or ribosomes, are responsible for actually producing proteins. Proteins are just long chains of amino acid molecules. Ribosomes are responsible for linking up the amino acid molecules in a very specific order that corresponds directly to the mRNA template.
Thus the DNA is TRANSCRIBED to mRNA, which is then TRANSLATED to protein.
This is the central dogma of molecular Biology: DNA -> mRNA -> protein.
The protein molecules that result may then float freely in the cell's cytoplasm (where they were produced), or they may go through a series of packaging systems, where they could then ultimately be released from the cell in a process called exocytosis.
A cell that contains large numbers of ribosomes would produce a large number of proteins. Ribosomes are the cellular machinery responsible for protein synthesis, so an abundance of ribosomes indicates high levels of protein production within the cell.
The insertion of a human DNA fragment into a bacterial cell could potentially enable the bacterial cell to produce a human protein or enzyme. This technique is commonly used in biotechnology to produce pharmaceuticals or study gene function.
Ribosomes produce the proteins needed in a cell
Think of ribosomes as the cell's protein factories since they are responsible for protein synthesis. You can envision them as little "ribosome factories" constantly working to produce proteins for the cell.
The two organelles that produce protein are the ribosomes and the rough endoplasmic reticulum. The ribosomes manufacture proteins for the cell through protein synthesis. The rough endoplasmic reticulum produces proteins here that are often secreted by the cell and carried by the vesicles to the Golgi apparatus.
Ribosomes produce proteins in the cell.

The Golgi Apparatus in the cell packages or modifies the protein for release and then exits the cell.

Protein The cell produces proteins by a process called translation. mRNA is translated at the ribosome into proteins.
Ribosomes, in the animal cell, are sites of protein synthesis. The rough ER produce the proteins, though.
Ribosomes are needed to produce protein in cells.
