A bacterium. Bacteria cells do not contain a mitochondria.
Protein synthesis begins in the cell nucleus. A given gene (made of DNA) is activated, and it then creates RNA which travels to the ribosomes of the cell, which are essentially microscopic protein factories. The RNA gives the design of the protein, and the ribosomes create the protein based on that design. The raw material for the proteins, which is amino acids, is already present in the cell's cytoplasm.
The rough endoplasmic reticulum is covered in ribosomes. In fact, it is called 'rough' because of the presence of ribosomes which give it a rough looking appearance. Technically, the rough endoplasmic reticulum is actually the region of the greater 'endoplasmic reticulum' where protein synthesis takes place. Another region of the endoplasmic reticulum is the 'smooth endoplasmic reticulum' where lipids are synthesized and other metabolic functions take place. The quantity of rough versus smooth endoplasmic reticulum is somewhat in flux and varies based on the needs of the cell.
Amino acids are made up of chains of proteins. Ribosomes produce proteins that are based on information in the mRNA.
That information is the genetic material (DNA).
The endoplasmic reticulum is the cell's interconnected network of vesicles and tubules, which enables transport and processing of proteins.

According to one hypothesis, once there was the ancestor of a eukaryotic cell, which swallowed a bacterium. But instead of digesting it, the eukaryotic cell used the bacterium to yield energy by feeding it. In other words, a symbiosis formed, where the former bacterium is protected from foes and gets sugar, whereas the eukaryote gets ATP.This hypothesis is based on the facts ofthe double cell wall of the mitochondria (the inner one rough like a bacterium one, the outer smooth like from a lysosome)the own DNA of the mitochondriathe 70S ribosomes (like bacteria have it) instead of eukaryotic 80S ribosomes
The endoplasmic reticulum is the one that surrounds ribosomes. This based on the fact that endoplasmic reticulum is usually stuffed with ribosomes.

In a cell, ribosomes make proteins with amino acids based on the RNA blueprints copied from the DNA.
Ribosomes are the site of protein synthesis. This is where translation takes place - the mRNA is read and a protein is created.
The Menity based on the reviews does offers a wonderful shave with the smooth look when it comes to a shave. Based on the reviews it also mentioned that the shave last longer then other creams that were used.
