Which type of cell has ribosomes?

• Prokaryote
• Eukaryote
• Both prokaryotes & eukaryotes

In a prokaryotic cell, the DNA is ________________.

• Wrapped around histone proteins
• Contained in the nucleus
• "naked" and "free-floating"

Which of the following is a correct list of structures found in both plant AND animal cells?

• mitochondria, nucleus, cell membrane, cytoplasm, Golgi apparatus
• mitochondria, nucleus, cell membrane, cytoplasm, cell wall,
• mitochondria, vacuole, nucleus, cell membrane, chloroplasts
• mitochondria, large vacuole, nucleus, cell membrane, cell wall

Which of the following is a key difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.
• Eukaryotic cells have a nucleus, while prokaryotic cells do not.
• Prokaryotic cells contain mitochondria, while eukaryotic cells do not.
• Both prokaryotic and eukaryotic cells are always multicellular.

Who was the scientist to identify and name the first "Cell" from a piece of cork?

• Anton van Leeuwenhoek
• Matthias Schleiden
• Rudolf Virchow
• Robert Hook

Eukaryotes usually contain

• a nucleus.
• specialized organelles
• genetic material
• all the above

Where is the DNA of a eukaryotic cell typically located?

• Nucleoid region
• Mitochondria
• Nucleus

Which cells have DNA?

• Prokaryotic
• Eukaryotic
• Neither
• Both

Which organelle would you expect to find in plant cells but not animal cells?

• mitochondrion
• chloroplast
• ribosome
• smooth endoplasmic reticulum

Plant and animals cells are both eukaryotic, and thus they are similar in many ways. However, plant cells have some organelles that are not present in animal cells. Which of the following organelles is not found in animal cells?

• a membrane-covered endoplasmic reticulum
• a large vacuole
• a DNA-containing mitochondrion
• a functioning Golgi complex
