• enzymes

• ribosomes

• DNA

Some unicellular organisms are motile (have the ability to move) and some are nonmotile. Which cellular structures are associated with movement?

• ribosomes

• vacuoles

• flagella

• chloroplasts

Which of these is the best model of a prokaryotic cell?

• F

• G

• J

Which characteristic of prokaryotic organisms makes them different from eukaryotes?

• Prokaryotes are made of cells.

• Prokaryotes have DNA.

• Prokaryotes do not have chromosomes.

• Prokaryotic cells do not have membrane-bound organelles.

The main difference between prokaryotic and eukaryotic cells is that —

• prokaryotic cells do not have a plasma membrane

• prokaryotic cells are always much larger

• eukaryotic cells don't have a nucleus

• eukaryotic cells are more complex

What characteristic do all living things share?

• They need oxygen to survive.

• They reproduce by mitosis.

• They contain DNA.

• They are made up of many parts.

How is the prokaryotic bacterium in the diagram different from a eukaryotic cell?

• It has no membrane-bound nucleus.

• It stores its genetic information in DNA.

• It has a cell membrane.

• It has ribosomes to make proteins.

Which of these statements best summarizes the cell theory?

• Cells contain a nucleus and other parts.

• Cells come in different shapes and sizes.

• Cells can be seen through a microscope.

• Cells are the building blocks of living things.

• Chloroplast

• Vacuole

• Nucleus

• Mitochondrion

Which pair of structures are present in plant cells and NOT in animal cells?

• Cytoplasm and mitochondria
