Which of the following consist of prokaryotic cells?
Ad libitum [116K]

The correct answer is D. Bacteria and archaea

Explanation:

In biology, cells can be mainly classified into prokaryotic and eukaryotic. The prokaryotic cells are cells with no nucleus or centrioles but they do have a cell wall, usually one chromosome and complex cilia and flagella. On the other hand, prokaryotic cells have a defined nucleus, multiple chromosomes, and centrioles and some have a cell wall. Due to the differences between these two type of cells they are part of different organisms, in the case of eukaryotic cells, these are part of the complex organism that includes animals, plants, and fungi while prokaryotic cells are those found in bacteria and archaea which are organisms with only one cell. Considering this, the ones that consist of prokaryotic cells are bacteria and archaea.
