Question

Which is the key difference between archaea and bacteria?

a) Archaea are prokaryotic while bacteria are eukaryotic.
b) Archaea can live in anaerobic conditions while bacteria can only live in aerobic
conditions.
c) Archaea can only live in less extreme conditions while bacteria can live in more
extreme conditions.
d) Archaea do not use photosynthesis as a source of metabolic energy, while some
bacteria can use photosynthesis as a source of metabolic energy.
e) Archaea have membrane-bound organelles while bacteria do not have membrane-bound organelles.

Answer 1

Archaea and bacteria are both prokaryotes, but they differ in DNA, biochemistry, and cellular structures. Archaea can thrive in extreme environments, while bacteria have a broader range of habitat preferences.

Step-by-step explanation:

The key difference between archaea and bacteria is that archaea are prokaryotic while bacteria are also prokaryotic but differ in their DNA and biochemistry. Archaea have distinct cell walls and plasma membranes compared to bacteria, and their ribosomal proteins are more similar to those in eukaryotic cells. Additionally, archaea can live in extreme environments, while bacteria can live in a wider range of conditions.
