Question

is the following statement true or false? all single-celled organisms are prokaryotes.
multiple choice
true, because all eukaryotes are multicellular
false, because all single-celled organisms are eukaryotes
true, because prokaryotes are the simplest cell form
false, because some eukaryotes are single-celled
false, because some prokaryotes are multicellular

Explanation:

To determine the answer, we analyze the options:

• Option 1: False, as eukaryotes like yeast are single - celled.
• Option 2: False, not all single - celled organisms are eukaryotes (e.g., bacteria are prokaryotic and single - celled).
• Option 3: False, the simplicity of prokaryotes doesn't mean all single - celled organisms are prokaryotes.
• Option 4: Correct. Some eukaryotes (e.g., yeast, amoeba) are single - celled, so the statement "All single - celled organisms are prokaryotes" is false.
• Option 5: False, prokaryotes are all unicellular.

Answer:

D. false, because some eukaryotes are single - celled
