Prokaryotic and Eukaryotic Cells Quiz

Which of the following is a characteristic of prokaryotic cells?

• They have a nucleus that stores DNA.

• Their DNA floats freely in a region called the nucleoid.

• They contain mitochondria.

• They have many membrane-bound organelles.

Which of the following is NOT a membrane-bound organelle found in eukaryotic cells?

• Mitochondrion

• Ribosome

• Golgi apparatus

• Endoplasmic reticulum

Why are eukaryotic cells capable of forming multicellular organisms?

• They lack specialized compartments.

• They can carry out many specialized processes at once due to their compartments.

• They have only one type of organelle.

• Their DNA floats freely in the cytoplasm.

What is the role of the endoplasmic reticulum (ER) in eukaryotic cells?

• Produces energy

• Processes and transports proteins and lipids

• Builds proteins

• Packages and ships materials

How do mitochondria and chloroplasts reproduce inside cells?

• Independently

• By fusion

• Through binary fission only in plants

• By budding from the nucleus

What model explains the origins of the mitochondria and chloroplast?

• Autogenous

• Endosymbiotic

• Biological

• Viral particles origination

What structures do prokaryotic cells lack that eukaryotic cells have?

• Nucleus and membrane-bound organelles

• Cell wall and ribosomes

• Cytoplasm and plasma membrane

• DNA and RNA

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

• Eukaryotic cells have a nucleus; prokaryotic cells do not

• Prokaryotic cells have mitochondria; eukaryotic cells do not

• Eukaryotic cells lack DNA; prokaryotic cells have DNA

• Prokaryotic cells have chloroplasts; eukaryotic cells do not

Some scientists think both the autogenous and endosymbiotic models may have occurred. What is a reasonable explanation for this view?

• Different organelles may have originated through different processes

• Only one model can be correct

• Both models suggest no organelles exist

• Both models reject the idea of evolution
