The answer is C. Bacteria.
Bacteria are prokaryotes, which means that they do not have a nucleus or any other membrane-bound organelles. Their genetic material is instead contained in a nucleoid, which is a region of the cytoplasm that is not separated from the rest of the cell by a membrane.
Viruses are not cells at all, but rather are simply a piece of nucleic acid (DNA or RNA) surrounded by a protein coat. They do not have any of the structures that are found in cells, such as a nucleus or cytoplasm.
Algae are eukaryotes, which means that they have a nucleus and other membrane-bound organelles. Their genetic material is contained in a nucleus, which is a membrane-bound structure that is located in the cytoplasm.
Moss is a plant, and all plants are eukaryotes. Their genetic material is contained in a nucleus, which is a membrane-bound structure that is located in the cytoplasm.
In conclusion, the correct answer to the question “In __ cells the genetic material is without any nuclear membrane covering and is directly submerged in the cytoplasm” is C. Bacteria.
