Question
Explain the statement that both types, bacteria and archaea, have the same basic structures, but built from different chemical components.
Step 1
When it says they have the "same basic structures," it means that both bacteria and archaea share certain fundamental features, such as having a cell membrane, cytoplasm, ribosomes, and genetic material (DNA). These structures are essential for carrying out Show more…

How do archaea and bacteria differ? How do prokaryotes and viruses differ?
Explain the statement that both Archaea and Bacteria have the same basic structures, but these structures are built from different chemical components. a. Typical cells in Archaea and Bacteria contain a cell wall, cell membrane, nucleoid region, ribosomes, and often a capsule, flagellum, and pili. However, these are sometimes made from different chemical compounds. Cell walls of Bacteria contain peptidoglycan while Archaea do not. Plasma membrane lipids of Bacteria are fatty acids while those of Archaea are phytanyl groups. b. Typical cells in Archaea and Bacteria contain a cell wall, cell membrane, nucleoid region and often a capsule, flagellum, and pili but in some instances different chemical compounds make them. Cell walls of Bacteria contain peptidoglycan while Archaea do not. Bacteria contain 70S ribosomes while Archaea contain 80S ribosomes. c. Typical cells in Archaea and Bacteria contain a cell wall, nuclear membranes, nucleoid region and often a capsule, flagellum, and pili but in some instances different chemical compounds make them. Cell walls of Bacteria contain peptidoglycan while Archaea do not. Plasma membrane lipids of bacteria are fatty acids, while the plasma membrane lipids of Archaea are phytanyl groups. d.
