Question at position 26: Which of the following is FALSE? Prokaryotes... include both Archaea and Bacteria.
Option 1: 'include both Archaea and Bacteria.' This is true, since the two main domains of prokaryotes are Archaea and Bacteria, both of which lack a membrane-bound nucleus.
Option 2: 'are not photosynthetic.' This statement is false because some prokaryotes are indeed photosynthetic, such as cyanobacteria, which perform photosynthesis much like plants do. So this option asserts something incorrect about the capabilities of prokaryotes.
Option 3: 'have circular chromosomes.' This is generally true for bacteria and many archaea; their genetic material is typically organized as a single circular chromosome, not linear like many eukaryotic genomes.
Option 4: 'are smaller than Eukaryotes.' This is true on average; prokaryotic cells are typically smaller in size than eukaryotic cells, though there is considerable size variation.
Option 5: 'lack mitochondria.' This is true for prokaryotes, which do not contain membrane-bound organelles such as mitochondria, as mitochondria are a feature of eukaryotic cells.
So, when identifying the false statement, option 2 stands out because it incorrectly claims prokaryotes are not photosynthetic, despite the existence of photosynthetic prokaryotic groups.
