Which statement best describes a difference between prokaryotic cells and eukaryotic cells?

• The presence of both DNA and ribosomes in prokaryotic cells indicates that they are more complex than eukaryotic cells.

• The larger size of prokaryotic cells indicates that they are more complex than eukaryotic cells.

• The larger size of eukaryotic cells indicates that they are more complex than prokaryotic cells.

• The presence of membrane-bound organelles in eukaryotic cells indicates that they are more complex than prokaryotic cells.

Which characteristic is shared by all prokaryotic and eukaryotic organisms?

• the ability to reproduce asexually

• the ability to make their own food

• the need for a source of energy

• the need for oxygen for respiration

Which characteristic is shared by both prokaryotes and eukaryotes?

• contain genetic material

• make their own food

• have organ systems

• need oxygen gas to breathe

2. Which statement best compares eukaryotic cells and prokaryotic cells?

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells are more complex than eukaryotic cells.

• Eukaryotic cells contain membrane-bound organelles, and prokaryotic cells do not.

The bacterium Acetobacter Aceti is found in acidic environments and has an acidic cytoplasm. For this reason, most of its proteins are able to function in acidic conditions. This property distinguishes Acetobacter Aceti proteins from those of most other organisms. Which characteristic does Acetobacter Aceti most likely share with other organisms?

• the method that the organism uses to reproduce itself

• the physical and chemical responses to environmental changes

• the type of organelle used to produce energy for cellular functions

• the process used to form proteins by transcription and translation
