Question

Juan received a class assignment to write about organisms that live in extreme environments. While doing research online, he found an image that showed microbial bodies thriving in hot springs. The organisms lacked a nucleus or defined organelles. Which organisms can he possibly find in such conditions?

A.
plant-like protists
B.
animal-like protists
C.
fungus-like protists
D.
archaea

Answer 1

That would be D. Archaea.

Archaea are prokaryotes. So they lack a nucleus and other membrane bound organelles.

Most species of domain archaea are extremophiles(for example thermophiles or halophiles) meaning they live in extreme environments where few or no other organism can survive.
