Exploring the Cell

What is the basic unit of life?

• Cell

• Atom

• Molecule

• Organism

Name the organelle responsible for energy production.

• Mitochondrion

• Nucleus

• Chloroplast

• Ribosome

What is the function of the cell membrane?

• The cell membrane generates energy for the cell.

• The cell membrane provides structural support to the cell.

• The cell membrane stores genetic information.

• The cell membrane controls the passage of materials into and out of the cell.

Describe the role of ribosomes in a cell.

• Ribosomes store genetic information in the nucleus.

• Ribosomes are responsible for cell division and replication.

• Ribosomes transport nutrients across the cell membrane.

• Ribosomes synthesize proteins by translating mRNA into polypeptides.

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells do not have a nucleus or membrane-bound organelles; eukaryotic cells do.

• Prokaryotic cells are always multicellular; eukaryotic cells are unicellular.

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells have a nucleus; eukaryotic cells do not.
