Summary Introduction
Introduction:
Three domains includes Archaebacteria, prokaryotes and eukaryotes. Archaebacteria has the 70S ribosome and plasma membrane. Prokaryotes also has both 70S and plasma membrane. Eukaryotes also 70S and plasma membrane. These are the two unique characteristics found in all three domains.

Members of the mycoplasma genus of bacteria do not have a cell wall for protection, existing with only a simple cell membrane made up of fatty acids and phospholipids. They cannot however, synthesize their own fatty acids. How is this possible?
A. They use host materials
B. They use peptidoglycan from other bacteria
C. They use anabolism as a way to create their outer membrane
D. They use amino acids to build their membranes
Which of the following is not found in all bacterial and archaeal cells?a. cytoplasmic membrane b. a nucleoid. c.ribosomes d. flagellum
Which of the following statement about the bacterial cell wall is INCORRECT?
a. The cell wall is relatively nonpermeable and restricts the passage of sugars and amino acids.
b. Gram-positive cells have more peptidoglycan in theircell walls than Gram-negative cells.
c. Gram-negative cells have a membrane both inside andoutside their cell walls.
d. The cell wall establishes a bacterium’s shape as a coccus,bacillus, or spirillum.
