What is one major difference between prokaryotic and eukaryotic cells?

Eukaryotes lack cell boundaries

Prokaryotes contain numerous organelles

Eukaryotes are generally much smaller in size

Prokaryotes are generally much smaller in size (correct)

What is an extreme example of cell size difference mentioned in the text?

Nucleus and mitochondria

Salmonella enterica and Paramecium protist

Bacteria and mitochondria

Epulopiscium fishelsoni (a large bacterium) and Mycoplasma pneumoniae (the smallest known bacterium) (correct)

What can be inferred from the image of a single human cell infected with Salmonella enterica serovar Typhi?

The bacteria are larger than the human cell
