As a general rule, practically all the internal organelles of a cell are covered by a protective membrane, except for one type, which couldn't even be called a real organelle, and those are the Ribosomes. More a macromolecular assemble than a cell organelle, the reason because they aren't membrane-bound is because they can directly interact with the membrane in order to exchange proteins, so, having their own membrane would actually act as a barrier for them to do their job correctly.
No, bacteria does not have a single membrane covered organelle.
Scientifically explaining, they are membrane-covered organelles that are found only in the eukaryotic cell. Prokaryotic cells do not have membrane-covered organelles. The only organelle they have, not membrane-covered, are ribosomes.

No,they are not covered.They are also in prokariyotes.
