no they are not surrounded by any membrane
Ribosomes.
An attached ribosome is a ribosome that is bound to the endoplasmic reticulum (ER) membrane. It is involved in the synthesis of proteins that are either secreted by the cell or inserted into the membrane. These proteins play crucial roles in various cellular functions.

A free ribosome is a ribosome that is not attached to any membrane within the cell. It synthesizes proteins that are used within the cell itself.
Ribosomes are constructed of RNA and protein.

Bacterial ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Additionally, bacterial ribosomes have fewer proteins and do not have as many modification sites as eukaryotic ribosomes. The antibiotic targeting sites also differ between bacterial and eukaryotic ribosomes.
The ribosome translates the mRNA into protein.

Some examples of organelles that could be present in both pro-and eukaryotic cells (it all depends on the species) are a: flagellum, plasmid (rare in eukarytoic cells, but not unheard of) and ribosome.
