Certain single-celled eukaryotic organisms may contain which of the following organelles?

• A. Ribosomes
• B. Mitochondria
• C. Nucleoid
• D. Peptidoglycan

Answer: (B)

Verified step by step guidance

1. Understand that single-celled eukaryotic organisms are characterized by having membrane-bound organelles.
2. Recall that mitochondria are membrane-bound organelles found in eukaryotic cells, responsible for energy production through cellular respiration.
3. Recognize that ribosomes are present in both prokaryotic and eukaryotic cells, but they are not membrane-bound organelles.
4. Identify that a nucleoid is a region where the genetic material is located in prokaryotic cells, not a membrane-bound organelle.
5. Understand that peptidoglycan is a component of the cell wall in prokaryotic cells, particularly bacteria, and is not an organelle.
