Which of the following would typically contain ribosomes?
(a) fungi (b) bacteria (c) Archeae (d) viruses (e) prions
To determine which of the options typically contain ribosomes, we need to understand what ribosomes are and where they are found.
Ribosomes are cellular structures that are responsible for protein synthesis in living organisms. They are composed of RNA and proteins. Ribosomes can be found in both prokaryotic and eukaryotic cells.
Now, let's analyze the options:
(a) Fungi: Fungi are eukaryotic organisms that include mushrooms, yeasts, and molds. Since eukaryotic cells have membrane-bound organelles, including ribosomes, fungi typically contain ribosomes.
(b) Bacteria: Bacteria are prokaryotic microorganisms. Prokaryotic cells also have ribosomes. In fact, the ribosomes in bacteria are slightly different from those in eukaryotes and are thus often targeted by antibiotics. Therefore, bacteria typically contain ribosomes.
(c) Archaea: Archaea are another group of prokaryotic microorganisms, and like bacteria, they have ribosomes. Hence, archaea typically contain ribosomes.
(d) Viruses: Viruses are not considered living organisms as they lack the necessary cellular machinery to carry out metabolic processes, including protein synthesis. While viruses can hijack the host cell's machinery, they themselves do not contain ribosomes.
(e) Prions: Prions are misfolded proteins that can cause certain diseases. They are not organisms and, similar to viruses, lack cellular structures such as ribosomes.
Based on the information above, the options that typically contain ribosomes are:
(a) Fungi
(b) Bacteria
(c) Archaea
So, the correct answer is: (a) fungi, (b) bacteria, and (c) Archaea.
