EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Bacteria are considered as prokaryotic unicellular organisms. Complete step by step answer:-They do not have the membrane-bound organelles like mitochondria, golgi complex.-They only contain ribosomes in the cytoplasm.

Detailed explanation-3: -Bacteria must have ribosomes because they are needed for protein synthesis. This is because ribosomes allow the protein polypeptide chain to be synthesized from messenger RNA. Without proteins, there can be no life since the enzymes which catalyze biochemical reactions are proteins.

Detailed explanation-4: -The ribosome is a universal biosynthesis machine present in all eukaryotes and prokaryotes. A bacterial ribosome comprised the small (30S) and large (50S) subunits which together form the 70S particle (Kurland 1972; Ramakrishnan 2002).

Detailed explanation-5: -Bacterial Cells They don’t have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.
