A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell?

• The cell would lack genetic information.

• The cell would lack the structure that is needed to produce energy.

• The cell would lack the structure that is needed to protect the cell’s organelles.

• The cell would lack control over materials that move into and out of the cell.

Which structure is unique to eukaryotic cells?

• DNA

• cell membrane

• ribosomes

• nucleus

What is the entire object shown in the image?

• prokaryote

• eukaryote

• chloroplast

• mitochondrion

A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified?

• The cell is prokaryotic because it contains ribosomes.

• The cell is prokaryotic because it contains mitochondria.

• The cell is eukaryotic because it contains ribosomes.

• The cell is eukaryotic because it contains mitochondria.

Which statement is most likely to apply to a cell that has DNA within its cytoplasm?

• It lacks ribosomes.

• It has membrane-bound organelles.

• It is multicellular.

• It performs all functions for the organism.
