The answer to the very question you are asking is "plants"
A Ribosome is composed of ribosomal RNA and proteins.
They are made in the cell nucleus, in two types of subunits, the large and the small.
The subunits go to the cell body, where they can float free in the cytoplasm or attach to the rough endoplasmic reticulum.
<span>The major difference between viruses and living cells is that viruses do not have nuclei while living cells do. A second major difference is that viruses need a host cell to survive while living cells do not. For the most part, viruses just contain genetic material (typically in the form of RNA) inside of a capsid. Living cells have many more organelles, including ribosomes and cytoplasm, which viruses lack.</span>
