Mastery Check 1.1.2

Which is a characteristic of prokaryotic cells?

• Prokaryotic cells contain DNA enclosed within a nuclear membrane.

• Prokaryotic cells are complex cells containing membrane-bound organelles.

• Prokaryotic cells are simple cells containing no membrane-bound organelles.

• Prokaryotic cells perform photosynthesis within their chloroplasts.

This is a diagram of a cell.

How would this cell be classified?

• as a prokaryotic plant cell

• as a eukaryotic plant cell

• as a prokaryotic animal cell

• as a eukaryotic animal cell

A student looks at two slides through a microscope. The student determines that Slide X is a eukaryotic cell, and Slide Y is a prokaryotic cell. Which structure would help the student make this conclusion?

• presence or absence of a cell membrane

• presence or absence of a ribosome

• presence or absence of cytoplasm

• presence or absence of a nucleus

How does the nuclear DNA in eukaryotic cells compare to the DNA in prokaryotic cells?

• Both cells contain genetic material within the nucleus.

• Both cells contain some genetic material inside a mitochondrion.

• DNA in prokaryotic cells has a circular shape, unlike eukaryotic cells.

• DNA is composed of amino acids in prokaryotic cells, unlike eukaryotic cells.

This illustration shows two different types of cells.

Which of these is a valid comparison of the two cells pictured?

• Both cells are equal in complexity.

• Both cells contain genetic information.

• Both cells transform energy using mitochondria.

• Both cells have a rigid, outer barrier for protection.

Which best describes what type of cell(s) contain a plasma membrane?

• eukaryotic cells

• prokaryotic cells

• both eukaryotic and prokaryotic cells

• all eukaryotic cells and some prokaryotic cells

Which explains why a eukaryotic cell is more complex than a prokaryotic cell?

• A eukaryotic cell lacks vacuoles and mitochondria, while the nuclear body is bound by a nuclear membrane.

• A eukaryotic cell contains vacuoles and mitochondria, and the nuclear body is bound by a nuclear membrane.

• A eukaryotic cell contains one circular chromosome, and the nuclear body is not membrane-bound.

• A eukaryotic cell contains pairs of chromosomes, while the nuclear body is not membrane-bound.

How are prokaryotic and eukaryotic cells similar?

• Both contain a nucleus.

• Both contain ribosomes.

• Both contain membrane-bound organelles.

• Both are types of cells found in plants.

Which would determine if a cell was a bacterial cell or a plant cell?

• the presence or absence of a cell wall

• the presence or absence of ribosomes

• the presence or absence of mitochrondria

• the presence or absence of genetic information

Which explains why eukaryotic cells can be larger than prokaryotic cells?

• because prokaryotic cells have a short life span

• because prokaryotic cells lack genetic information

• because eukaryotic cells are found in all living things

• because eukaryotic cells contain organelles with unique functions
