Fiona and her friends were watching a TV show about organisms found in the subtropical forests of southern China. These organisms were acid tolerant and lacked most internal organelles. Which organisms could they most likely be? A.
amoeba
B.
archaea
C.
dinoflagellates
D.
algae
E.
euglenoids

The answer is: B - archaea

Explanation:

The organisms found in the subtropical forests of southern China which were acid tolerant and lacked internal organelles are the Archaea. Archaea refers to the domain of life with organisms living in extreme conditions. Because of this, the Archaea are referred to as the extremophiles.

The cells are very small, prokaryotic and are similar to bacteria in lacking a nucleus and membrane bound organelles. The cell membrane is bounded by a cell wall. They reproduce by binary fission, fragmentation or budding.

They can tolerate high temperatures and survive in hot springs, anaerobic conditions and are acid-tolerant. These acid tolearting Archaea are called the acidophiles surviving in a pH of 2 or less than 2.

They pump out protons out of the intracellular space and thus keep their cytoplasm in a neutral pH or have an acidified cytoplasm. The example are Thiobacillus acidophilus, Crenarchaeota and others.
