Question

Bacterial and archaea are prokaryotes, therefore

a. They must be monophyletic
b. They both have a nucleus
c. They have a cell wall
d. They lack organization inside their cells
e. They have a phospholipid bilayer

Answer 1

Prokaryotes (domains Archaea and Bacteria) are single-celled organisms that lack a nucleus. They have a single piece of circular DNA in the nucleoid area of the cell. Bacteria and Archaea differ in the lipid composition of their cell membranes and the characteristics of the cell wall.

Step-by-step explanation:

Prokaryotes (domains Archaea and Bacteria) are single-celled organisms that lack a nucleus. They have a single piece of circular DNA in the nucleoid area of the cell. Most prokaryotes have a cell wall that lies outside the boundary of the plasma membrane. Some prokaryotes may have additional structures such as a capsule, flagella, and pili. Bacteria and Archaea differ in the lipid composition of their cell membranes and the characteristics of the cell wall. In archaeal membranes, phytanyl units, rather than fatty acids, are linked to glycerol. Some archaeal membranes are lipid monolayers instead of bilayers.
