Which characteristic is not true of the archaea?
a) all members of the archaea are prokaryotes.
b) they have plasma membrane phospholipids that are identical to the eubacteria.
c) many are extremeophiles that tolerate hostile environments.
d) they are more closely related to eukarya than they are to eubacteria.

They have plasma membrane phospholipids that are identical to the Eubacteria.

Explanation:

Archae includes mostly the single celled prokaryotic organism that lacks the membrane bound organelles. Most archae are extremophiles that can tolerate the extreme environment.

Archae shows more similarity to eukarya. The plasma membrane of archae contains of pseudo peptidoglycan that differs form the plasma membrane of the bacteria.

Thus, the correct answer is option (b).
