Detailed explanation-1: -Prokaryotes are predominantly single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.

Detailed explanation-2: -The cell membrane contains all of these components, which are essential to the bacterial cell’s survival. Hence, Bacteria contain both cytosol and cytoplasm.

Detailed explanation-3: -All living cells including bacteria contain cytoplasm within their cell membranes. The cytoplasm surrounds the nucleus in eukaryotes or nucleoid in prokaryotes. It consists of the cytosol and the cell organelles, such as ribosomes.

Detailed explanation-4: -In bacteria, the cell wall forms a rigid structure of uniform thickness around the cell and is responsible for the characteristic shape of the cell (rod, coccus, or spiral). Inside the cell wall (or rigid peptidoglycan layer) is the plasma (cytoplasmic) membrane; this is usually closely apposed to the wall layer.

Detailed explanation-5: -Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria.
